I can't recommend store brand at BJ's and Costco enough. Also, they have the best wipes as well. I have twins and we bought diapers and wipes by the case and ended up with memberships at both Bj's and Costco. We tried every store brand on the market and their store brands worked wonderfully. Plus, their wipes were more fabric like than all the name brands...the boys are 7 and we still keep those wipes handy.
Good luck
Jules
