Summit customer service can't be beat. Great return policy, good prices. May NOT be cheaper than the local parts store, but if you buy in bulk ( filters, wires, plugs, etc ) then in the long run you do save money not having to run around.

last order from Summit, I got three oil filters, some air filters, couple sets of plug wires, HEI dist. caps... Seems like a trip to 'town' takes half a day. "stitch in time" and all that..
