Man its your moneys, do wat u want, but if u think about it, these coupon happent many many time from advance, and the 30% off coupon is not like 1 in the life time where I spend all on oil filter, coupon like 10 dollar off on 30 spend or 15 off on 40 or 50 spend, not too long ago bosch and pure 1 have rebate, using those code above got big discount then plus rebate, at the end you pay really nothing or free. if i remmeber correctly few month ago bosch distant have rebate and with advance auto discount code above total came out free oil filter.
what im trying to say is, this coupon is not a big deal where to go all out and spend all on 5+ years worth of oil filter. and have to worried about oil filter life or ants or something dig in and eat the inside created a big hole and you may or never know about it when install on your car. or the seal getting dry so cause of many year and created leak ( saw it happent to one of the member here ) if you like motorcraft oil filter just go to walmart and pay 45-50 cent more EVERY DAY when ever you need it. and that filter is very popular filter and peoples buy it every day or every other day, and got restock with fresh filter.
if you storage oil filter, This is wat my grandpa told me, turn the filter gasket side up, and put a light coat of fresh oil and cover it with a ziplock bag, and seal it with a rubber band, and put gasket side up inside the box, it keep the seal lube and keep unwanted thing craw into the filter.
