I would like to purchase some new release sports cards from a hobby
distributor in the DFW (Dallas-Ft.Worth TX) area.  This is where most
hobby shops (aka "Card Shops") get their stock - Topps, Upper Deck,
Donruss/Leaf/Playoff, etc.  Cards are bought by the case (multiple
boxes, where each box contains packs of individual cards) and I assume
there is some sort of minimum order to set up an account or make a
purchase.

I would like information on one or more distributors (tip for more
than 1) in the DFW area who do this type of business.  I have an
established business entity in-state with a Texas Sales and Use Tax
Permit so I'm not an individual simply looking for a deal on cheap
cards.  Name, address and phone number for each distributor at a
minimum, and any other information you can provide would be helpful. 
Not looking for internet retailers like dacardworld.com or
blowoutcases.com - they are fine companies but I am looking for an
actual wholesaler/distributor in the local area.

Thanks!
