What this site is, and how the deals on it are checked.
This is an independent savings guide for one small job: keeping the current oil change coupons of the four big chains, Jiffy Lube, Valvoline, Firestone and Take 5, in one readable place. Each brand page lists the offers that are running now, the dates printed on them, and a direct link to the brand's own coupon page, because that official page is always the final word.
Offers are checked against the brands' official coupon and offers pages. When an official page moves a date or ends an offer, the listing here is refreshed to match. Expiry dates are printed next to the deals on purpose: a coupon roundup that hides dates sends drivers out with dead offers, and that helps nobody.
This guide is not affiliated with any of the chains, and it does not sell anything. It exists because the same service can cost $30 less with ten seconds of checking, and most drivers never see the coupon their own store is running.
