How about drink/food coupons at events? You can even sell back your unspent ones (if the organiser isn't a dick!)
Well it would be a option which could be considered in future. But selling back the unused coupons? Not sure how this should work. But it would be great if promoters would sell coupons you could use on every event of the same promoter. Most fans are going to a lot of events from the same promoter so they could use them anytime they need the coupons.
I also think that would be difficult to sell back unspent ones, just make sure you used all of them! Drink more beer
It would be nice to have same coupons on different event, like events on the same location but different day.
There is a bright future in this kind of platforms!!
Keep it up
Not sure if it such a great idea. You probably need to pay transaction fees and maybe other stuff? I would prefere coupons which would be usable at different events.
