I think the idea is a great one, Im just wondering if WGT is hesitant in doing this because you are essentially offering the same product for a cheaper price.
A used club versus a new club does not differ in the virtual world, therefore WGT would expect to make a profit from the transaction aside from just the replacement of the sold driver/wedge/irons etc...at least that is what I see as the potential problems.
In doing so, they are dealing with very small margins...What would they charge for a transaction? 10 credits, 20 credits, 50, credits? I imagine used drivers and wedges would be going for a price that is not too much more expensive than that, although I havent looked at the prices in a little while.
I dont know the economics behind it, or what exactly would go into the feature from a programmatic perspective, however I do think it is a great idea and one that would foster the community and enhance connections between users.
