I ordered 2 oil filters for 2 different cars and then wiper blades which were closeouts for a third car. The filters came from warehouse A, the wipers from warehouse B. The $7.50 cost for both wipers had shipping of $10.99. I decided to cancel the wipers as I really didnt need them. Once I did this the two filter were then changed to ship from 2 different locations which really doesnt make any sense for me which naturally increased the shipping cost.. They originally were to ship from the same location. I cancelled my order. I had been a long time Rock Auto customer but will rethink this going foward.
