Where can I buy Color Oops (hair dye remover), Color Zap, or something of the sort?

[Graham Cracka Snacka]

I searched walmart.com, kmart.com, and target.com for 'color oops' but nothing came up. Grr!! I don't want to order it off Amazon but I suppose that might be my only option, huh? See, in my town, there's a Walmart (which is my go-to because my mom works there), a Kmart (hardly ever go there), a Target (UGH), a Walgreens (I think), a Safeway, a Longs Drugs (do they sell dye sorts there? No clue), and like ten gas stations (among random other little clothing shops, kitchy little tourist places, and - duh - restaurants). So, among the places I've listed, do any of them sell Color Oops, Color Zap, something with the same effect?

Thanks in advance =]
