Not the lowest price ever but very low. Lowest ever was the frontpage deal at Staples from late January 2017 for $16, but that included tax, and for me that ended up being $16.96 after tax (PA at the time). In this case, there shouldn't be tax for most buyers. Their webpage says they are located in NJ. My previous order with them had no tax (I'm in VA).
Easy to miss, but it says it is refurb (HT Pctek4456)
It is built real well and the button response is real good. The multi-device functionality is really nice. It supports up to 3 devices.
My experience with iTechDeal is a neutral one, but other have had success. I ordered 3 of those $1 USB C cables that was Frontpage back in August. They got lost in the mail. However, I contacted the company and they were very nice and refunded me my order. They offered me to re-ship them, but I declined.
