Wal Mart, Target and Kmart sell Gerber and Leatherman tools, and SAKs also although I've never seen any Vic plier based tools in any of those stores.The best prices though can be found online. Every brick and moarter store I've been in charges outrageous prices for their multitools.EDIT:Army surplus stores somethimes have a bunch of multitools...but again the ones I've seen have been expensive. The good thing about surplus stores is sometimes you can find discontinued, rare or otherwise interesting tools that you might not find elsewhere.
If you have a COSTCO or SAM's Club membership check the tool section, sometimes they have Leathermans or SOGs combos at reasonable prices. www.walmart.com has plenty of models from Leatherman, SOG, Victorinox, Gerber and many more, they can ship the tool, for free, to your local store.RegardsGuillermo
