Want delicious salmon for dinner without running all over town? Buying seafood online gives you access to a wider selection, from sashimi-grade fillets to bulk 5 lb cases of scallops, often at better prices than your local fishmonger. Shopping online also makes comparing brands, sustainability labels, and pack sizes simple — you can filter by wild-caught vs. farmed, check whether items are IQF (individually quick frozen), and spot deals on family-sized portions. Think of it like having a whole seafood market in your pocket.
Walmart is one of the big names that shows up when people search for seafood online. The retailer carries everything from frozen chopped clams sold in 5 lb cases to sashimi-grade salmon bundles, and catfish fillets in 2.5 lb packages. If you want a one-stop shop, Walmart’s assortment covers both everyday staples and specialty items — plus you’ll often see bulk listings that are useful for meal prep, parties, or stocking the freezer.
Some entries you’ll see include Sea Watch frozen chopped clam meat sold in 5 lb cases, premium dry sea scallops in 5 lb packs, IQF catfish fillets in 2.5 lb bags, and New Zealand mussels in 2 lb packs. There are also sushi-grade salmon options and dehydrated seafood toppings for ramen or snacks. These prepackaged sizes make it easy to plan meals and compare unit prices in pounds or ounces.
If you cook seafood regularly, those 5 lb cases are worth a serious look. Buying in bulk reduces the per-pound cost and gives you flexibility — thaw individual portions as you need them. For example, a 5 lb bag of scallops can yield several weeknight dinners and a special weekend sear. Just be sure your freezer has the space; bulk buys are great if you can keep items vacuum-sealed or tightly wrapped to avoid freezer burn.
One surprising name that sometimes appears in seafood searches is Armed American Supply. While known mostly for tactical gear, niche or nontraditional retailers occasionally list food items, specialty supplies, or survival-oriented freeze-dried seafood. If you encounter these listings, check product descriptions and shipping details carefully — they may be aimed at long-term storage or emergency kits rather than everyday dining.
Beyond general retailers, several specialty shops and clubs in the US focus on high-quality seafood. These sellers can offer traceability, seasonal freshness, or artisan handling that mass retailers can’t always match. Whether you want sustainably harvested wild salmon, sashimi-grade deliveries, or freshly caught items shipped overnight, specialty retailers are often your best bet.
Warehouse clubs like Costco and Sam’s Club excel at offering large-format seafood — think multi-pound salmon fillets, family packs of shrimp, and frozen scallop bags. If you feed a crowd or want to stock the freezer, club memberships can pay off. Their frozen offerings often come in multi-pound packages that keep cost per pound low.
Whole Foods and reputable local fish markets focus on freshness and responsible sourcing. You’ll find whole fillets, fresh shellfish, and clear labeling for wild-caught or sustainably farmed options. These places are great if you prioritize flavor and provenance over bulk pricing.
Online specialists such as Vital Choice and Sea to Table emphasize traceability and wild-caught products, often shipping fresh or flash-frozen seafood right to your door. Fulton Fish Market and similar platforms can connect you with fresh, market-grade catches. These retailers are ideal when you’re after restaurant-quality fish and willing to pay a little more for premium handling and traceability.
Choosing seafood online can feel risky, but a few checks make it easy. Look for clear descriptions, standards like "sashimi-grade" or "IQF," and transparent origin details. Photos and customer reviews are helpful clues, and packaging descriptions (vacuum-sealed, insulated shipping) tell you how likely the product arrived in top condition.
“Sashimi-grade,” “never frozen,” and “IQF” are terms you’ll see a lot. Sashimi-grade generally indicates a product suitable for raw consumption and tight handling standards. "Never frozen" is useful for fresh fillets when available, but top-quality flash-frozen items can match or beat fresh in flavor because they’re frozen at peak freshness. IQF means pieces are frozen individually so you can thaw single portions without clumping.
Origin matters — Alaska salmon, Icelandic salmon, and New Zealand mussels each bring different textures and flavors. Certifications like MSC (Marine Stewardship Council) or ASC (Aquaculture Stewardship Council) signal sustainable harvesting or farming practices. If sustainability matters to you, filter for certified sellers or ask for catch method and region information.
Look for vacuum-sealed packs, insulated boxes, and gel ice or dry ice shipping. For longer transit, frozen and vacuum-packed is usually safest. If a listing shows pack sizes like 2 lb, 5 lb, or 16 oz, make sure those sizes match how you cook and freeze — smaller portions make thawing simpler, while larger packs reduce cost per pound.
Whether you’re a seafood novice or a committed fish lover, here are top varieties to try along with simple cooking ideas that deliver big flavor without fuss.
Salmon is the crowd-pleaser: broil, grill, pan-sear, or bake it. A 1 lb salmon fillet cooks quickly — about 10 to 12 minutes in a 400°F oven — and you can seal flavor with a simple honey-soy glaze or lemon-butter sauce. For sashimi-grade salmon, keep it chilled and slice thinly for poke bowls or sushi-style plates.
Dry sea scallops in 5 lb packs are often sold frozen for restaurants and avid home cooks. Thaw scallops and pat completely dry, then sear in a hot skillet with a little oil for about 1.5 to 2 minutes per side until a golden crust forms. Serve on a bed of mashed potatoes or with a citrus butter for a fast, elegant meal.
Mussels sold in 2 lb bags or clams in multi-pound packs are inexpensive and simple. Steam them in a shallow pot with white wine, garlic, and butter for 5 to 8 minutes until shells open. Discard any that remain closed. Serve with crusty bread to soak up the broth.
Catfish fillets (often packaged in 2.5 lb bags) are great for pan-frying or blackening. Coat in cornmeal or a spice rub and cook in a medium-hot skillet for 3 to 4 minutes per side. Catfish holds up well to bold seasoning and makes excellent tacos or po’boys.
Good handling is the secret to great seafood. Frozen seafood can last several months in a home freezer if kept at a steady temperature, and vacuum-sealed packs help prevent freezer burn. For best texture, thaw frozen seafood in the refrigerator — a 1 lb fillet typically thaws overnight, while a 5 lb case may need 24 to 48 hours. If you’re in a hurry, submerge vacuum-sealed packs in cold water, changing the water every 30 minutes until thawed.
Simple techniques elevate seafood. Pat fish dry before searing to get a crisp exterior, season just before cooking to avoid drawing out moisture, and finish lean fish with a pat of butter or a squeeze of citrus for brightness. Shellfish benefit from gentle heat: overcooking turns scallops rubbery and shrimp tough, so aim for a quick cook at high heat.
Want great seafood without breaking the bank? Look for seasonal specials, buy in bulk like 5 lb cases or multi-pound packs, and consider club memberships for lower per-pound costs. Subscribe-and-save options at specialty retailers can reduce price and keep a steady supply on your schedule. Also, check for frozen options — they often cost less than fresh and can be stored for months, giving you flexibility.
Watch out for vague product descriptions and weak photos. If a listing lacks origin, pack size in pounds or ounces, or storage details, it’s wise to move on. Also be skeptical of "sashimi-grade" labels without explanation — quality varies, and only some sellers meet the strict handling needed for raw consumption. Finally, avoid seafood that smells off or shows signs of freezer burn like discoloration or ice crystals.
Buying seafood online opens up a world of flavor and convenience — from economical 5 lb cases of scallops to premium sashimi-grade salmon for special meals. Use pack sizes, labels, and origin details to guide your choices, and don’t be afraid to try a mix of general retailers like Walmart and specialty sellers for the best balance of price and quality. With a little planning and the right storage, you can keep your freezer stocked with tasty, restaurant-caliber seafood ready to make weeknight dinners feel special.
Conclusion: Whether you’re feeding a family, cooking for one, or planning a dinner party, the US market has plenty of retail and specialty options. From Walmart’s wide selection of 2 lb and 5 lb packs to online purveyors that ship sashimi-grade fillets, there’s a convenient path to great seafood — all it takes is a few smart checks and a little culinary adventure.
