The Raspberry Pi 3 Model B+ comes in at the usual $35 USD price point. I was able to buy a unit for testing shortly after launch from Adafruit, but to little surprise a few days later most of the retailers are already out-of--stock on the Raspberry Pi 3 Model B+ or at some are not yet stocked in the first place...
The reviews online have been good. But I think we should give some more time for a more holistic review and feedback.
As for the stalls out of stock, Lol. Lets hope it's not a trick for more sales by the retailers.
