Not sure what exactly the kind of place your looking for, but Ive been filling my 1 gallon jugs up at superwalmart at the culligan RO water machine. Its 33cents a gallon. I guess it could be iffy the quality of water you get depending on the servicing of the machine and all, but it cheaper than buys the already bottled distilled gallons of water at 69cents a gallon.
DOn't know if this helps at all, sometimes hannaford has these RO machines too.
