Terrible business practices. I placed an order on a Friday for a fairly expensive rifle after receiving multiple emails advertising the price and a subsequent notification from the company that it was back in stock. I didn't receive shipping info so I followed up with them the following Friday and was told it would ship by the end of that day. Then Monday I got an email saying "thanks for your order" followed immediately by another saying they were issuing a refund. So basically they tied up a few thousand dollars of my money and screwed me around for 10 days, lied about it, then told me they didn't have the rifle in stock so it would be refunded... in another 5-7 business days. Frankly I don't believe they actually have the items they advertise - it's just a ruse to get people in the door.
UPDATE: The first two purchases were each for magazines and one of them had to be returned because it was wrong. It's one thing to ship a magazine promptly (and correctly 50% of the time); it's quite another to aggressively market a deal on a rifle you don't have and then BLATANTLY LIE ABOUT IT when I contact you a week later to make sure you have it in stock. The fact that they tried to share my order history in a pathetic attempt to discredit me - conveniently forgetting to mention that they messed up half of them - only reinforces my opinion and proves how sleezy their business practices are.
