Found the Supermarket Sweep game at one of the Atlanta-area Ollie's locations, $4.99 as mentioned above. It was on the board game aisle and not in the seasonal section, so look in both places if you need to.
If I recall, the companion app is no longer supported for SS.
The App still works, they updated it in July and changed a few things. The only thing we have issues with are the Bonus Inflatables, they seem to be a different style of UPC barcode and will not focus and scan. We just make our own rules there.
I asked the company about it and they said they were working on another refresh of the App and that was on the list, but I dont think they have fixed that aspect yet, if they even plan to at all still. However, the regular products scan just fine!
