Before fishermen discovered the edibility of fish, they used each catch as bait for larger species, hoping in the end to hook the biggest fish of all—friendship. Land a pal for your palate with today's Groupon: for $15, you get $30 worth of fresh-caught seafood from Pacific Foods. Redeem your Groupon quickly, it expires December 9.

Pacific Foods stocks its icy racks with fresh seafood from California and other global locales, creating a travel agency for landlocked taste buds. Because the fishmongers stock a larder flush with fresh-caught live dungeness crab year-round (market price), patrons can sate crab cravings perpetually or train up a crustacean army of tap-dancers. Other deep-dwelling delicacies include similarly armored live lobster ($17.50/lb.) and oysters ($20 for 25), or the boldly bare monterey calamari ($7.50/lb.). Shrimp abounds, from wild caught Mexican varieties ($18/lb.) to titanic types that weigh in among the heaviest available in America ($25/pound). Wonder at the diversity of Neptune's realm, with piscine meals such as tilapia ($25/10 lb. case), wild-caught scallops ($17.50/lb.), and extra-large Alaskan king crab legs ($24.50/lb.), which may be enjoyed in rich melted butter or held aloft as a warning against potential crab rebellions.
