Amazon has the 1st gen Google Pixel 32 GB for sale at $315 with free shipping for Prime members. It is a new phone sold by 3rd party sellers.
Pros: Even though this phone is two years old, it still holds up against most mid-range phones today, and you get Google backing + Amazon backing for this purchase. It will get the Android P update at the same time as other Google phones.
Cons: Limited storage of 32GB (but comes with unlimited cloud storage on Google Drive). I wish the bezels were a bit smaller!
