1 box went from 37 to 57 in the span of less than a month. I do believe Wayfair changes prices for you based on your purchase habits. I’ve purchased 7 boxes or so. These tiles are just okay. If too much liquid goes between them, they’re done and you have to pull them upthey’ll pretty much just loosen and curl up at the corners. I’ve already had this happen. I won’t use self adhesive tiles ever again... these will eventually have to be replaced entirely. Hopefully not too soon.
