Thanks OP for the heads up.
It’s a little late now as the promo expires tomorrow, however figured I’d post anyway as it sounds they run similar promotions every so often.
I just got off the phone with a Mobil rep who works in the promotions department. They’ve advised that they will honor the promotion for “just about any retailer, with the exception of Amazon.com”.
I bought two 6-packs at SAMs last month for $27.78 (should be $2.63 a quart after the promo), however I’ll probably stop by Wal-Mart tomorrow and stock up on 0w-20 & 5w-20 for my girl’s car. They’re offering $22.88 for the 5 quart jug, which comes out to $2.18 a quart after the promo. Can’t beat that!
The last day to submit for the rebate is 6/30/18. I'm going to try to finagle and use my Dad's address or my gf's name or something, in order to buy moar oils.
FYI - per the Mobil website their synthetic motor oil is good for 5 years. I just bought my 4Runner this past Saturday and I receive an oil change from Toyota at 10k and one at 20k. So even if I stock up, I should utilize the oil before 'expiration'.
