*%*#!* ROCKAUTO SHIPPING ALGORITHM ?!!*!?!

Rock Autos profit is in the shipping . It’s obvious when you order 4 common parts and they all come from different warehouses. There is no way a major retailer selling to millions of people only stocks 1 of each item per warehouse! I only order from them if it’s a large order .
I got 4 Bosch 02 sensorfrom them . Didn’t order them or pay for them but I got them …lol
I once ordered a set (16) of chrome moly retainers from Summit and they sent me 16 boxes of them ! Lol
