Wyze recently resdesigned their website and backend, and switched their shopping partners, so adding the “notify me when it is back in stock” has to be reconfigured. It is under active development and will be re-enabled as soon as they have that feature ready again. ETA on the Air purifier is partially subject to manufacturing and shipping issues in our current global economy and last I heard [today] it will be a while:
They were definitely very, very popular and in high demand and sold out the first 2 shipments extremely fast.
For future consideration, what I have done in similar situations, is order items while I know they are in-stock or available and at a cheaper rate, and then contact the shipper (Fed-Ex or whoever it goes through once the shipping label is created) and have them hold it for me until I return home.
When they come back, I expect the price will be at the standard price of $169.99, possibly with a discount for the Cam Plus members, but it’s possible they could extend a cheaper rate as low as the $129.99 again. I wouldn’t count on it though, I think that was just the launch special…you never know though, and I expect they will have other deals throughout the year anyway as usual.
