Help purchasing TGE for a friend

GG I want to purchase the TGE for a friend. I own TSE,TGE,TLK, ragdoll, and planning to purchase the RTS, and Showtool this Saturday. I have a friend that always helps everyone in thier programming, homework, ect. He recently talked about getting the TGE to Start his final project for school. I was wondering how I would how or if I would be able to purchase it for him. I really want to show him that I appreciate all his help and he said he does'nt have the money for it just yet but he's been such a friend and I just want to help him get started on his final project. BY th way we both are attending Collins College for Game Design. They teach the Unreal engine editor not the TGE.
