Is there a "best" way to purchase materials at wholesale sellers?

[NM_Shooter]

Trying to find some marble tiles for my lingering bathroom remodel.  Went to a showroom yesterday, and found that they only do wholesale.  Went to another showroom... also only wholesale. 

I guess I could probably form a business and get a tax ID, or find some contractor who will buy for me at a premium. 

Arghhhhhhh......

(anybody know any good flooring / tile places near Albuquerque?)
