Anyone use Sam's Member's Mark diapers?

Well, we do (since we can diaper twins for the price of a singleton who is diapered with Pampers or Huggies), so I asked DH to get some when he went to Sam's yesterday. He called me to ask what the box looks like, so I described it to him and he looked some more, finding only the Member's Mark training pants, but no diapers. He asked a clerk and was told that they don't carry them any more! Their own store brand diapers?!?!?!? Excuse me? That was one of the main reasons we joined Sam's. Has anyone else run into this problem? The last time I bought diapers was at the other Sam's in town and they seemed to have a normal, plentiful amount of all sizes. I looked online to see about ordering some through their Click & Pull program and found that the other store now only has sizes 4 and 5 in stock! I guess if they truly have discontinued them we'll change to Costco! Does anyone know what's up here?
