My favorite story about best buy is in the early 2000’s, a family member gifted me a $20 gift card to best buy, which unbeknownst to them, I had stopped shopping at because it got too expensive and I started buying from newegg instead. Anyway, I walk in and am thinking 'well I don’t really need anything big right now, like a full PC, laptop, etc. Maybe I’ll just get a DVD or something."

Even with a $20 gift card, Best buy prices were so marked up, they were either still more expensive, or the same price as other stores. I think other stores were selling DVD’s at like $15 (not new-releases) and best buy was $35. I walked out and never ended up buying anything. I’m shocked they’re still around to be honest.

I can confirm the xdrip app works on grapheneOS, currently use it on a pixel 8a

Yo, from one type 1 to another, get yourself some xdrip to replace the dexcom app, its miles ahead and more configurable.

And depending on which omnipod you got, and how technical you are, check out AndroidAPS if you want an open source closed-loop solution.

If you got the omnipod dash you can use it directly with AndroidAPS via Bluetooth.

I use both of these with dexcom G6 and an accu-chek Bluetooth insulin pump, and its amazing vs the commercial solutions.
