4x Purolator oil filter for $15, free shipping

[victorb]

Purolator has a rebate going on: $3 off / filter, up to 4 filter (i.e. up to $12). The only catch is that it's a mail in rebate (which I will probably forget to send back).

Ordering from amazon.com, 4x PL14610 = $15.24 after rebate, free shipping.

Rebate form attached.
