I just pre-ordered one for $159.20 at
www.vapenw.com. They are having a 20% off Black Friday sale on everything in the store including pre-order items. The discount code is 20%offBlackFriday. The code will only work when you're logged into their site.
I was going to wait until Black Friday to see if any other stores had a better deal but I figured I should jump on Vape NW's sale now before they sold out of their of their incoming order. Their sale just started on Sunday.
I hope this info helps out people who are looking for a great deal on a SX Mini ML.
