I was looking at Reflexive stats for my game UBM (reflexive is a very good portal, with real-time stats for developers). I was surprised to notice that about 90% of orders come within the in-game order form and only a few using the traditional webpage!
I really didn’t expect a so high percentage. Hope my vendor Plimus add the in-game purchase option soon, it seems that is a very common system… 🙂
