I'm still looking for a site with reasonable shipping. I go to these sites, do an imaginary order for something like 800 2x2's, five dansco album pages and 50 air-tites and shipping is consistently over $10.
I thought you could fill a box for $10 with USPS priority mail. ONE site listed $24.95 as the shipping cost (yes!).
So check out shipping before you jump.
I'll be honest, if you don't have a lot to buy, troll through the hundreds of e-bay listings and find the one that is the cheapest for exactly what you want.
Secondly, this is also one area where it may be cheaper to stock up big time at your local coin dealer - even though his/her prices might be higher. Just figure in shipping!! And you should really be supporting your local coin stores too.....
