Concerning the comment by FSUpaintball that any CUSA rebate problems are not due to CUSA, but due to the manufacturer, please consider this: CUSA *CHOOSES* which suppliers to use. If they opt to sell items from suppliers/manufacturers who give (or claim to give) rebates, they accept some of the responsibility (at lease moral responsibility) of the rebate. Pushing blame onto the people whom you've chosen to team with is completely unacceptable. CUSA intentionally advertises the products with the rebates prominantly (sp?) noted. By doing that, they are condoning however the rebate-giver operates.
Think about it - If you buy a $100 piece of equipment from CUSA with an advertised $50 rebate, then the rebate never comes through, you have still paid CUSA $100 for that equipment. Understandably, CUSA will get hosed by some manufacturers on rebates, but if CUSA continues to advertise that manufacturer's product with rebates, they are ultimately at fault, and will catch any negative vibe.
(This is not intended to be a rant on CUSA, but on ANY business that uses the same business practices. FSUpaintball just happened to mention them by name.)
