Very nice! Congratulations!
From a long time ago I'm trying to build a e-ink magnet for the fridge with relevant updated relevant information about some school programs.
But I haven't really found a cheap e-ink display.
Edit: I see that you answered it:
>Bought off Alibaba, I think they're so cheap because they're designed for grocery store shelf price tags. Good Display GDEW029T5D Where do you get yours for $20?
You can get displays from Adafruit for $22 [0] or from Waveshare [1] even cheaper if you're willing to do a little more work. I've used both and they're both pretty nice.

Oh the display is only like $4-6 on Alibaba. After you add the resin and my custom PCB it's like $20 at the low scale I'm purchasing.
Actually, the cards already have magnets in em, so these would work on your fridge already.
But you need a base station to update them, and a way to connect to your network to upload images/text.....
If you email me your address, I'd be happy to send you one for your fridge :D
