This is actually a repost of my coupon terms.
When a store is having a BOGO promotion. It will depend on the stores' coupon policy how many coupons can be used with that purchase, Some stores will allow 2 one for each item ,other stores just 1. When you present a BOGO coupon to the store and they are not running a bogo promotion. You must present 2 items for each coupon. You must pay for one of those items. If the store is having Buy one get half off and you present a bogo coupon. You still will only have to pay for one item. You can also use two manufacture's coupons for that deal.
If you have another question. Please post in your reply.
