Are you citing subsidized prices, or used prices? I can only find $80 Motorolas used or locked, e.g.: https://www.amazon.com/dp/B0D323V72S and that's 4GB

12GB seems to get up into $200+, and that's still a lot of "renewed" listings.

You can find quirky little loss-leader deals here and there sometimes but I don't think you're getting 12GB of RAM for $80 on a routine basis.
