Advance Auto Parts offers select Purolator PureONE Oil Filters
for $5 each. Better yet, add six
to your cart and apply coupon code "A123" to get them for $20
($3.33/filter). Shipping adds $9.42, so it's best to opt for in-store pickup
if available. Even if you can't get them for pickup, that's still the lowest total no-rebate price we've seen for these filters. (Most merchants charge at least $10 each.) Sales tax is added where applicable.
