Paypal Cashback Credit Card + RebatesMe (or similar) 7% back at Walmart

I just wanted to alert folks of a nice little system that I found to get 7% back at Walmart (at least for the stuff that WM gives cashback for).

I simply just go to RebatesMe for 4% back on Pet Supplies, Beauty/Body, etc, order it for In-Store Pickup and checkout with Paypal to my Paypal Cashback Mastercard.

So basically RebatesMe will give 4% back then Paypal/Paypal CBMC will give 3% for using Paypal with the Mastercard.
