I'd like to introduce a new passion project of mine I started called 8bitedge.com. Think of 8bitedge as a game identification service for arbitrage on market places. Identify games at good prices from a market place like eBay, either using the web console or the desktop integrated console (it's really cool actually). Price out lots of games by setting profit margins, selling fees, etc. using gaming insights and real time pricing data updated daily. Perfectly price out your profit on your purchased games! Price out games and predict profit margin prior to buying multiple games! It really is a useful service to identify retro games at the lowest price point.
In addition to arbitrage features, you have access to recent news feeds on different retro platforms, top game lists updated hourly and more!
8bitedge.com is a free service and fully supported by donations, so please, if you find it useful and you enjoy the services, don't hesitate to donate as it keeps the lights on!
You can access all services at https://8bitedge.com.
Thanks and enjoy!
