Bensbargains has an Amazon deal for a 5 quart jug of Mobil-1 synthetic motor oil for $23 with a $12 rebate, limit 2 per household. This rebate pops up a few times a year, and I usually go to my local dreaded Walmart. This time I decided to use up some of my Amazon gift card credit instead and avoid a trip to my unfavorite store. Much to my surprise, when I ordered two jugs, I got a $10 Discover promotion credit. Discover is the default credit card, but the entire payment came from the gift card credit. I don't remember doing anything to get this promotion.
Total before tax for two jugs is $35.76, less $24 rebate, giving $5.88 for 5 quarts of Mobil-1. And for some reason, it's eligible for free 1-day shipping (I have Amazon Prime).
