Depends on how fast you want it. Order today Monday and get it Friday on Amazon or pay $18 for the same ship dates on Speedway.
If you're willing to wait another 4 days which most of us are, Speedway is the definitely best. AC Delco filters are ~5,50
Amazon
Speedway (Same delivery day as Amazon)
Speedway (4 extra days for free ship)
...and with the 1st time purchase discount... Speedway FTW.
