I was at CVS yesterday and looked at Biore products. I know the deal is spend $15 get $5 ECB, but each product is on sale for $7.29. If I buy 2 as suggested, it works out to $14.58. Does anyone know if that will still kick out the ECB? Or do I need to look around for another product for about $1 that would qualify, since there are several brands in that deal?
