The Epic Games Store has an interesting interaction going on right now – the short of it is that by “buying” Rocket League – which is now free to play – you’ll get a $10 coupon good for any future purchase on any game that costs $14.99 or more.

There’s no need to actually install Rocket League, of course, unless you want to (it’s addicting with friends).

And if you’re scratching your head thinking of how to best use your $10 coupon, the original poster on Slickdeals recommends getting Star Wars Squadrons ($30 after coupon).

Either way, it’s a solid deal that might not last.
