Just curious Ben, but why don't you buy supplies on line from one of the many dealers who've been mentioned here in other threads? If I don't buy them at coin shows, I buy my 2x2s and plastic album pages from one of them, and generally pay less (including S/H) than I would at either of the coin shops located within 5 miles of my home.
Hmmm, well as far as mail goes we've got some substandard delivery issues which just can't seem to be ironed out by the USPS, nothing missing just odd behavior by the delivery rep. The fewer items (packages) received here, the better. Then again, never really needed that many supplies to warrant a special order. I did get some (10 Coin World like) plastic holders and a couple of coins from www.mintproducts.com and the order took 15 weeks to arrive. Just not worth it...
