BOGO Coupons

Remember when I talked about BOGO coupons here?  I decided to email Coupon Information Corparation (CIC) and Proctor and Gamble (P&G) to see what their view is on using both a BOGO and cents off coupons.   They both agree with me and say NO.  I did ask P&G to be more specific in their answer.  Here are their responses to my email:

CIC:
Thank you for your inquiry Hannah,
The following is taken from our "Voluntary Best Practices: Retailer Coupon Acceptance".  This document will be posted on the CIC Website shortly.
BUY ONE, GET ONE FREE COUPONS (BOGO)
1.     BOGO coupons cannot be “chained”  (i.e., two BOGO coupons cannot be used to on two items to get both for free).  Unless stated otherwise on the coupon, the use of one BOGO coupon requires that two of the valid items are presented at checkout; one item will be charged to the consumer and the second item will be discounted by its full retail price. 
2.     In a BOGO transaction, a second cents-off coupon cannot be counted towards the purchase price of the first (buy one) product.

P&G:
Thanks for getting in touch with us, Hannah.
We appreciate you taking the time to verify our coupon policy.   Use of more than one manufacturer coupon per product is strictly prohibited.
Coupons were designed to provide value to consumers, help retailers build trial, and build loyalty of P&G products.  Limiting quantities will benefit consumers by protecting against stock depletion, and protect retailers from coupon fraud and other inconveniences.
I hope this information is helpful.
