Arnold, I got on the Tractor Supply website and ordered in a 2.5 gallon jug of Shell Rotella T6, regularly priced at $54.99. Combined with a "Honey" coupon of $5.00 off, it brought the cost down to $49.99.
I then took advantage of your link to the Shell Rebate page, entered my info and uploaded my Tractor Supply receipt, then submitted the form for a $17.50 rebate. That brought my total cost down to $32.49. That's $23.51 that I saved had I bought it instead at Walmart!
I would never have even been aware of this good deal if you hadn't made your post. Granted, I wasn't able to secure an incredible deal such as yours, but I STILL saved a ton of money. I'm grinning like the proverbial Cheshire Cat. Thank you!
