Tax no Tax is not an issue at Staples.
The bulk of their business is not the retail customer looking for a dozen pencils.
Over half of their business is B to B. Businesses need more than amazon has to offer in services, breadth of line one stop shop. Business customers are not concerned about paying tax. Retail customers are and that customer is not a Staples customer to begin with. That is already a Big box, chain drug store or your Amazon customer looking to save on Tax.
So I am not bashing but that is the way it is
