gamestop's pretty much funded all my gaming for the past 4 years, for a while it was pretty easy to buy used games on sale weeks for $20-30 and trade them in for $45-51 a week or two later, do that across 50-100 games in a weekend at 3-4 stores and use that trade credit on new games. All my consoles have been bought at gamestop from trade deals, like them offering $300 for my launch PS4 and buying a PS4 Pro for $399 and a year later doing the same buying a God of War PS4 Pro. I've churned a good $50k+ of credit through them and have thousands of xbox/psn/eshop cards that will fund digital buys when gamestop goes away. Probably 90% of my game buys now are digital but whenever trade opportunities come up I still do it, albeit they are far less frequent and very short windows - the last one was in april when they offered $51 in trade credit for switch games for a single day due to some promo stacking.
so i'll be sad to see them go but more for the fact that they were severely incompetent and easy to take advantage of if you knew what you were doing. sadly as fewer and fewer people shop there (most stores are empty now when I go) they have really ratcheted down the deals/glitches.
Whats crazy is that there are still like 24 gamestops in my town, like Starbucks many are within 1-3 blocks of each other too.
