I can't speak to making a purchase at shooter's vault, but I did go shopping there and the person I spoke with was very helpful. He spent over an hour talking/educating me about guns I was interested in. I can't say that everyone who works at shooters vault is great, but if the service I received is any kind of representation I find it hard to believe that they would steal clips out of a new box...There is also the possibility your local gunshop opened the seal. Maybe you have a relationship and trust them, but it is possible (could be a new worker or disgruntled employee). Either way it would be good business to try to fix the problem.
