Once we run out of our first stash of cups, I bet she changes her mind. For whatever reason, she didn't seem too crazy about buying one of those crates of 1000 cups they sell at Costco, so she may have no other alternative.
And for the record, for this first stash, we did what was mentioned earlier in the thread and found a sale at Kohls and used one of their Kohls cash coupons.
