I cannot guess how much I have spent at Rock Auto. Several thousands, at least an order a month for six - seven years. Never gotten free shipping
When I started doing is looking at shipping locations and if something is needed add items that ship from the same warehouse for my stock on hand. They charge a high charge for even one filter. Say 9.00. But order six and shipping may be 12.00. But order three small items from three different warehouses and shipping may end up at 30.00.
Back on topic, Ordered four XL’s for the new Subaru 2.5l. Not as nice as the black Subaru filters from Japan. Those look like an origami artist folded the pleats in media. But those never were a 3.86 a pop filter.
Will start using the XL filters after the four free dealer oil changes are completed. The Subaru US filters are rebranded Fram with paper end caps.
