That's an easy one...
Thier website has a Contact Us page for retail stores
http://69.8.223.148/dsgcontactus/Makes it pretty easy to explain to them that I will not be shopping in thier store anytime soon as the only thing I go into one for is firearms and ammunition. The two local to me don't carry squat for camping and I could care less about golf and trendy sports clothing.
Just went into Corporate:
I read under a press release that Dick's will not be selling or displaying firearms in response to the violent attacks in Newtown CT. I personally believe hat that sends the wrong message to the general public. Yes, it was a tragedy and there should be dialog as to how to prevent something like that in the future, but to deny the rest of the population access to legitimately purchased sporting goods. Limiting firearms sales is not the answer. Firearms are used by millions for sporting and recreational purposes everyday with very few incidents of injury or death. It is not until one is mishandled or someone that should not have access to the firearm gets a hold of one that there is an issue. Instead of not selling them, how about donating a portion of the sale to the families and community? Dick's is shown to be charitable to the community; additional sales could be brought in by those looking to purchase a rifle but were undecided. Instead I know of a group that has already decided that if you don't want our money, we won't give it to you, and not just in the short term.
