Keep all of your steam receipts in a folder and keep them for all of eternity. A number of times I almost bought a game I already returned but forgot about. Had I not checked that folder before buying, I would have re-bought a shity game I already returned.
Been there done that. XD
Great advice. :thumbsup_tone1:
I still have saved the email I got when you gave me Hyperdimension Neptunia 2 <3
But yeah, I almost bought a game that I already own not so long ago lul
