when someone comes into the store in an attempt to return a generator, how much attention do you give him? "oh, nice to see you, I'll roll that generator over here and you'll get credit immediately". Or is it this way, "groan, %$^&.....der's nutin rong with that gen. Wait here while I look fo da managamint. " Half hour later, some clerk comes up and says," manager for generators not here today,come back next thurswedssaturday but wrap it in original packaging, we don't accept returns with any scratches and ask for Tony.
I seriously doubt Lowes cares if consumers bring back used generators because they come back in the store for the return and buy more stuff. Believe me, the manufactures like Generac eat the loss or refurbish and sell to someone else in a different market channel. Lowes is already paying you to be there and look pretty. Now get back to work.
