The diapers and wipes are the main thing I'm seeing, too. I can really use them with a 2yo and a baby on the way. Not sure about the Babies R Us brand. Is this just new branding for Especially for Baby? Those were always OK (not the greatest, but they worked for us). The wipes, though, will definitely work for me. But if I have the money to spend that day, I may just check with Babies R Us on my lunch break (I have to go to work at 4:30 am, so no early bird shopping for me) and check them out. I've had luck getting BF diaper deals there at that time before.
I use the BJs brand for my son and they have done a lot better then every brand except pampers, and i would say they are equal to pampers. I just bought a box of 165 ish diapers for $22 last weekend. I would stock up there and avoid just going to TRU for them on BF
