I was thinking maybe the autopricer could be sold as an item in cash shop? It could be some key of the sort with which we can unlock the autoprice feature.

I think that would decrease the amount of GAs being bought; I know quite a few people who buy them just to autoprice each day. With a Cash Shop autopricer, it would be a one-time purchase.

It's already sold in the Cash SHop for $5, it's called a Gold Account Medal
