just an update, I wrote to Elevate about this, and they were very quick to troubleshoot it. I got my full 2x points b/c now Automotive (excluding tires) counts as "Home" category through their Walmart link.

The store portal is still going through growing pains, but based on my experience it's worth the effort even with the errors. You just need to be diligent as well and follow up on lost award amounts.

IMO, this is the cheapest and easiest way to renew and get more elevate points.

B/c I use my VX credit card on the purchase, this $45 ($49 w/tax) purchase got me the equivalent of 7.3% cash back on my purchase (in airfare dollars), much better than most other credit card bonus cash back offers, and I bought something I needed, and at a cheap retailer. Icing on the cake is that, there's also a mail-in-rebate for this oil from the manufacture, which I didn't compute into this 7.3% figure, taking into account of my anticipated rebate credit, I would have gotten 13.3% cash back in airfare dollars for this!

Also, b/c this was my first purchase, I will also get a 500 point bonus.
