When I was looking for floodies Walmart's biggest was a DC27 marine at 105 or 115 AH. They've disconinued warranties for deep cycles though, so I stuck with the others I had seen at Sams. Sams was full of idiots but after 3 months and getting several managers involved I got a set of DC29's (125AH for $75 ea). They also have a number of golf cart options or optimas etc.
My DC29's give me 26 miles at 50% DOD in a VW bug running 120V.
