Wallmart carries "Bell" chains which aren't too bad, so long as you never get them wet. They have a 1-3 speed chain, which has pins sticking out, a 5 speed chain, which is your generic 1/8th inch works on the Schwinn Varsity sort of thing and the "Speedy Chain" aka 3/32. If you have 9speed or up they don't sell a product for you and honestly, just buy a SRAM chain at the LBS.
