It happens, @walkonby ! I find that if I'm early on the day of the FPC redemption, I tend to be the first customer showing the coupon to a cashier who might not know about the FPC promotion. So there's no queue behind me while s/he looks at the offer and ponders it before ringing it in.
Be prepared on Saturday-it's busy.
I have the July 8 Old El Paso FPC tortilla bowls wub dinner kit marked in my planner-coincides with OTB receipt day, so the grocery store will be my second stop after the bank visit.
