I'm new at this and confused..I have 5 of the 4.00 Glade Wisp Coupons. Do I have to go through check out 5 times, each time using my 5$ gift card, or can I purchase 5 candles and and 5 gift cards in one transaction with my 5 coupons? If you do have to check out 5 times, do you typically do it all in a row (just get back in line or something, or do you have to leave exit check out and go to another line or somthing)?
