It's not cost-effective to drive all over town when you're shopping for bargains; what you pay in gas is likely to offset any real savings. What you need is a single spot with numerous stores for the frugal-minded -- a spot like Central Park Center, a thrifters' paradise in southeast Denver. This mall features not one, not two, but three of the best bargain-basement stores in the area. On the prowl for a serviceable coat? Try your luck at ARC. Looking for a plastic lamb to nestle in the front lawn? Big Lots might have just the thing. And if shiny new housewares and cheap wrapping paper get your heart beating faster, Family Dollar has what you want. Misers, start your engines!
