- The smartest house July 4 sale. Includes a nice discount on the Dome water valve as well as a smaller discount on a number of other items. They’ve already said they don’t expect their prices to be lower on prime day. @jkp already started a thread on that one.

I think this is the regular monthly sale. Excellent prices on Z wave smart bulbs and the GoControl smart switch cover. @kevin already started a thread on that one:
- iDevices has 20% off site wide. These don’t have an official SmartThings integration, but they do have a good IFTTT channel, and one of the only in wall outlets where each socket Can be individually controlled. That works pretty well with an IFTTT integration.
Discussion thread:
- Best Buy has a bunch of items on sale in their smart home and security department. Nothing super exciting, but a lot of 15 to 25% off on Arlo, google, etc. $5 discounts on TP Link Kasa WiFi items, which finally, as of last month, have an official SmartThings integration. Also a good discount on the Wemo mini, probably to bring them in line pricewise with the TP Link models.

- Walmart
Looks like they’re holding off on big sales until prime day, when they are planning a huge event. They do have some Google devices on sale, a bunch of smart televisions, and, interestingly, some Apple products including iPads and Apple Watch. I guess they were looking for things that weren’t likely to be on sale at Amazon on prime day. 
- Hubitat has their hubs on sale for $10-$20 off this weekend.
- Home Depot
Has a bunch of Google devices on sale, as well as some Schlage and Yale smart locks. Note that the geeni Wi-Fi brand which they carry is not compatible with SmartThings. If you’re looking for that type of WiFi device in that price range but wont smartthings compatibility , check out TP Link Kasa instead.
