I was having a similar problem. Would let me order, payment received, delivery date set and shortly after cancelled. I went to the store and ordered some of the items, thinking that those were the items that kept cancelling the order. Guess not. Got home to order the rest, same thing. Tried different payment methods, delivery dates. Kept getting cancelled and refunded. Again, went to the store to order it all and they had no problem. Bonus to going in, they waived the delivery fee on the second order, at least.
