I am a subcontractor and shopped at Lowe's for a long time and never had a problem on till now since they changed over.I always buy different things and see which one works best and I return the ones that I did not use. Sometimes I lose the recipe and normally they check the card u used and you get your refund. Now if you don't have your receipt they scan your items and make sure it's their product and they give you a store credit only for less than you paid I was told it was about $1 less on every item.So I am going to drive the extra 5 or 10 minutes to HOME DEPOT where I know I will get my money back even with out my recipe because they look up the items and card that was used and refund with no problems.
