you need to count the ounces and weight for a good deal....if all clay is basically the same, then divide the ounces and price to com eup with where to find the best deal
but if some clay is more aggressive, then take that into consideration when purchasing...
personally I have this stuff that I found on ebay which looks very similar to the topoftheline stuff (same box packaging and everything) and it sucks! It takes multiple passes to start removing fallout compared to some yellow clay I used about a year ago, but I can no longer find that clay! I should have stocked up on it because it was only 15 bucks for 8oz and worked really well! yeah - 8oz of clay for 15 bucks!!! stupid stupid stupid....lol :wall :wall :wall
