I was surprised, today, to discover that a recent order of cleaning products coded as "U.S. Construction Materials."

In case anyone is curious, the vendor is Speed Cleaning. They sell their own line of concentrated cleaning products, and are geared toward small cleaning business owners, not just retail sales. Still, never in a million years would I have guessed they would be classified with Home Depot and Lowe's.

Anyone have any other surprising 1.5x point vendors?

I'm new to the AmEx Platinum (Business) and wouldn't mind maximizing my points earned on this card.
