Our Sam's Club takes the formula checks. BUT, tell them NOT to run it through the check reader because it always eats the dumb checks and messes up the machine. I would tell the cashier to call a manager over ahead of time to troubleshoot and let them know to run the checks as CASH which is what they always do at our Sam's. Otherwise you might be standing there forever and making people mad, haha.
