Any Costco members here also part of Sam's Club? I joined recently because AMEX is reimbursing the first year's membership fee and Sam's Club is offering a free upgrade to Plus for new members -- which includes the ability to shop starting a 7 am, a huge perk that Costco doesn't come close to providing.
That said, what kinds of food tend to be a better purchase at Sam's Club than Costco, if anything? I searched for articles online and most of them point to the prescription drug benefits but nothing really about food.
