If there was, I believe I would now be doing shopping at someplace OTHER than Staples:
Staples Says Gun Store Can’t Enter Contest
I agree with the owner of the gun store here...the most distressing part of this is Staples lumping firearms/weapons with illegal drugs and all the other activities that are usually targeted by sin taxes. Never mind that that are trying to help promote small businesses, and businesses don't get much smaller than some gunsmithing operations I've seen.
Oh well. They have the right to set up their contest the way they want, and I have the right to spend my money where I want. Office Depot was closer to my house and more convenient anyways...but now I will go out of my way to avoid giving Staples one red cent.
