Allcho vacuum insulated stainless steel water bottle, double wall, 18 oz $5.99
Amazon Add-on item price from 5.99 and 6.99 depending on color.
I was looking for a vacuum bottle to hang from my backpack or put in my car cup holder. Found these 18 oz'ers. There are very few reviews but all good. This price is several dollars less than eBay. As far as I could tell, I was not charged sales tax in CA. Thanks.
