Here's a tip for my fellow couponers:
Question: How does a Buy One Get One (BOGO) coupon work if there is also a BOGO promotion?
Answer: When a store has a BOGO promotion on something such as shampoo you can get both bottles for FREE! Here's how it works: Find a BOGO coupon from the manufacture in the newspaper or on the Web. Bring it in during the promotion. The cashier should charge full price for the first bottle and zero for the second. Your coupon makes the first bottle free. You pay nothing. If the store insists you purchase an item, buy three bottles. You pay for one, get one free form the sale and one free with your coupon.
