Just throwing this out there for people that are interested in this. I just placed a ~$400 order for another vehicle with Tower, and ended up getting a pretty good deal I think, and everything I did should translate directly over to those looking to purchase a $389.99 Optima Mid.
If you become a Premier Super Saver with Tower, until the end of the month (June 2022), you get $75 off any order over $370.

To become a Premier Super Saver member, you first have to become a normal Super Saver member, which is free, and then upgrade to Premier, which is $10. So, for your Mid order, you would actually be saving $65 off list price.
Tower also has free shipping on orders over $99 (normal folk) or $75 for Premier folk.

Now, if you don't want to become a Premier member, you still get $55 off and free shipping, so it only costs you $10 more than being a Premier customer.
