You can get plain flip-flops for under $15. And Keds, when they're on sale. :-)
Oh, where? At K-mart?
Keds? real Keds? i spent thirty-two bucks on plain white Keds sixteen years ago! btw--Star does those Payless Shoes commercials... i'm sure some of those shoes are $15... but that Sex and the City girl would never have worn them...
