I bought one on eBay a while back and took it to HD to purchase insulation for my garage...... $800 worth. Checked first at the service desk and the guy there said it was good. Go back to the register that is closest to the service desk, because I have a pallet of insulation, and the fellow that approved the coupon told the cashier to run the sale. Then she asked for his manager code for the discount, and he was busy, so another manager punched in his code. Then he looked at the coupon and asked where I got it. I told him that it arrived in the mail, which was the truth, since the seller mailed it to me. Head outside with the insulation and am loading it into the trailer, and out comes the store manager, and all the assistant managers. He informs me that the coupon is a forgery. I offer to bring the stuff back inside and void the sale, or pay the difference. Their choice.. He said that he would let the sale go through, but would be notifying the other stores about the forged coupons. I made sure to take an extra long time to load the insulation, in case he decided to call the police. I didn't want it to look like I was trying to pull one over on him, because I truly thought that they were good coupons. I paid with my credit card also, so they do know who I am, in case there are any questions. After having that one experience, I doubt that I will ever buy another coupon on eBay. I did email the seller and told him that the coupon was a forgery. He immediately refunded my money! Guess that he knew that it was a forgery also, and didn't want me telling PayPal about it. Now, I see that the auctions have changed and they say that they are not good at all HD stores, and especially not accepted in New England....
