In order to take advantage of the Checker rebates on oil - can I make all my claims on one form? Or do I have to send in separate forms for every purchase that qualified for a rebate? Anyone know? I can't remember the other members name other then he lives in Utah. I know he buys this rebate oil all the time and I'm starting to see the "wiseness" of his ways. Reason I'm asking is I have two coupons one for shell and one for valvoline. Would be more economical for me to get the rebate on one stamp instead of two stamps.
