"Wholesale sales" shall not include a transaction whereby property is delivered to and collection for same is made from a person that will consume the property rather than resell it even though the billing is to a retailer. Provided, however, when a taxpayer sells merchandise and has paid a rate equal to the retail rate of tax on the purchase price to a wholesaler, the taxpayer may take credit for the tax paid to the wholesaler from the tax due on the sale of the merchandise specifically included in his return to the Commissioner.
