Mary Kay sales tax collection on business taxes.

I am working on my independent contractor taxes for my Mary Kay business. As a wholesale provider, Mary Kay charges you sales tax on the full retail price of the item you purchase, even though you purchase at wholesale cost (50%). You then charge your customers sales tax to recoup this, thereby Mary Kay basically pre-charges you sales tax.

My question is can you deduct the sales tax that Mary Kay charged you, since Mary Kay has already paid this and you are in essence paying this again on your taxes? If so, where do I put it?
