We've got the MG90S for $5.99 when you buy them in a five pack. We have very nicely priced motors as well.

I am impressed. Most shops in my area pricing is higher that yours. One of them have no idea of customer service. The owner treats you like an idiot when you ask questions. The only reason I use them at all is to find little parts that the newer shops don't have.
