I work for Lowe's and posted item number, location, manufacturer, shippin unit, etc. If you buy the stuff at some roofing outlet, you have a very limited return policy because usually you are dealing with pros. Go to big box, ie Lowe's, Home Depot, etc. you have a much more friendly return policy as long as you bring the P/S with you. If you need more information, give me a PM with your zip, city, closest lowe's and I will tell you where it's located within the store, also cost, etc. If that Lowe's doesn't carry it, I'll tell them to order it for you but you have to buy a shipping unit. I believe there is a quantity of 12 in a shipping unit.
