The sale is on Pinnaclewax.com only, not autogeek.com.
Just a heads up in case you were going to order on autogeek.com. (I know I was for a minute

)
The e-mail seems a tad confusing given that it is sent from autogeek and signed at the bottom from autogeek.
I have used all the leather products and really, really like them. You can use them without fear of hurting your leather. They leave a nice leather smell and a matte, non greasy finish. They are very light with their cleaning ability so you may need a bit more aggressive cleaner if you have heavier dirt or stains. They condition the leather nicely. They won't restore damaged leather.
I use them on more refined leather found in BMW, Mercedes, etc... I stick with less expensive products on coated leather for cleaning and protecting.
The
tire gel, in my opinion, is too expensive. I have never used it however. Maybe if I had a show car and I liked the product, I'd buy it. But for daily drivers, I like good old Armor All by the gallon at Costco
As far as the MF products at Autogeek, I LOVE the Magic Towel that is currently on sale 3 for @ $15 I believe. I also like their WW towel. Those are the only two that I use from them.
