You can always swing by
http://bitmunitions.com and see if we carry some good ammo at prices you are willing to pay! (Hint: We sell all products 15-20% BELOW USD market value. Great way to get extra value from those bitcoins you have.)
Also I agree the
https://en.bitcoin.it/wiki/Trade might be the best resource for customers looking for merchants.
I placed an order at bitmunitions on 5/8 and am still waiting on an update. I was told it would be ready to ship on 5/10-11. Havent received a tracking number or the order and havent gotten any response from multiple emails to try and get a status update.
I have had a great experience with bitcoinstore though, and plan to order from them again.
