Hey all, I’ve been curious about this and finally took the time to contact Wyze support via email. Here’s their response:
Currently, our authorized sellers are Wyze, Target.com (shipped and sold by Target ), Chewy.com (shipped and sold by Chewy ), Amazon.com (shipped and sold by Amazon.com, does not extend to international Amazon marketplaces ), MicroCenter, PetSmart , Home Depot , Walmart, Best Buy, Costco, eBay Wyze Direct and select Amazon Books locations in the U.S.
eBay Wyze Direct is selling refurbished and used stuff at good prices with greater or lesser guarantees.
Read the listings carefully, ask the seller a question if in doubt. Also look at the seller feedback and especially filter for the neutral-to-negative responses. You are taking some risk of time and trouble (notwithstanding the guarantees) so make sure you’re up for that.
