Look into CoolStuff in Florida. I’ve been sending my bulk there because their 25% bonus applies to bulk cards as well, and they are generally more reliable in terms of delivery times than T&T. I get my CoolStuff packages in Alberta after about seven business days and only costs around $5 to ship, whereas the typical T&T package comes without tracking and costs $11 to ship.
To save money on shipping bulk, buy 800 count boxes from any card store … They usually hold 1140 to 1150 cards each. Put 8 of those into a big paper box (like the ones you can pick up at Staples). That should save you a bit on shipping costs. Shipping from Alberta to Orlando is usually $90 on 9000 cards, but I’ve paid $60 for just over 3000 cards the first time I did it. It gets cheaper the more cards you manage to get into the box.
(When you use their VIP program, the prices are equivalent to T&T on virtually all Pokemon singles.)
If this sounds too much like an advertisement for them, I apologize. I have no commercial interest in the site; just a very happy customer.
