1 coupon per purchase VS 1 coupon per transaction-

I want to tell the differences between 1 coupon per purchase and 1 coupon per transaction. This often gets confused.

1 coupon per purchase VS 1 coupon per transaction-

Once in a while, you will get some inexperienced checker who will tell you that you can't use your 10 coupons for cereal for your 10 boxes. She will say, It's one per purchase! Yes, she is absolutely right, its one per purchase. I am purchasing 1o items, so I can use 10 coupons. Each item is considered a purchase. Every item together is considered a transaction. Unless the coupon says one item per transaction, then you are safe to use all your coupons!
