After reading your article, I went to my local CVS with my coupons & their coupons. They would not take a second coupon on BOGO vitamins. The manager said if the register doesn't accept it, they won't take it. On my next visit, the cashier told me I could only use one coupon per item, so I had to choose between their $10 off $40 and their register coupon of $4 off $25. The item I bought was $50, so even after the $10 off, it was still over $25. The cashier would not even try to scan it to see if it would go through.
