First time poster, please hurt me.
I was looking for a tablet and was settling for the Samsung Tab A 10.1 model 2019 (about $500) until I came across this (lucky I could even top up with my last year's ebay discounted gift cards). I was looking at around $400 price range but I hope I did good taking one of them the S4 thinking it would be more future proof.
Knowing that Hardly Normal sells it at an inflated price of $1179, I thought that I'd compromise a little and get it used.

I don't know if that may help you or not, hope it does (hope also I made a good call buying this before seeing the deal on Ozbargain or hope not that people didn't post it because it was a ripoff …).
Horrible deal for a used tablet.
