Once you add shipping, i think they're about the same. I seem to use slightly less CK than KY though, so that might make a bit of a difference as well. But, then again, you don't have to wait for the mail with KY... lol, all depends on where your priorities are.
And Love2Knit: LOOB and CK/KY are not the same thing lol. I know the names can be confusing. LOOB is L'oreal out of bed, a creme 'texturizer' that you can find at most drug/grocery stores.
