MTD 01006913 OEM WHEEL ASM-CASTER

I have not yet received my order because it was just placed yesterday. What I wish to comment on is the refund given me on shipping. The OEM Parts Store had no obligation to refund me as I had already agreed to the amount indicated for shipping and handling at the time of the purchase. It takes great integrity for a company(individuals within the company) to return funds to a customer when cost incurred to ship an item was less than proposed. Wow! Well done! As need arises for parts, you guys are the place I will search first.
Happy New Year!
