I was looking for the lowest offer for PuyoPuyo Tetris and could not find anything better than $24.99. GameStop has preowned games as well and if you are a club member you can get it there at a lower price (physical copy). Download ver. is still available on Nintendo's site.
For those of you who did not want to purchase electronic copies here are some pre-owned cartridges:
1-2 Switch - $24.99
ARMS - $39.99
Disgaea 5 Complete - $39.99
LEGO City Undercover - $29.99
Minecraft Story Mode: The Complete Adventure - $27.99
PuyoPuyo Tetris - $24.99
Soldam: Drop, Connect, Erase - $24.99
Super Bomberman R - $24.99
The Binding of Isaac: Afterbirth+ - $29.99
Ultra Street Fighter II: The Final Challengers - $29.99
Some prices are good.
I figured rather than downloading I would rather have a cartridge that I can sell later. To be fair, PuyoPuyo Tetris weighs only 1Gb so it doesnt take that much space.
