Price in shop down to minimum (1 coin), as fast as up to maximum.
The way it's possible getting price in shopsales up to maximum works fine, it would just for many be nice being able getting the price down to minimum, as fast as it getting price up to maximum.
Many will probably ask why? The answer is simply, that many higher levels enjoy giving different items away to lower levels in NH, or lower level contacts found other places. For many it just feels nice, right and a good way to help some lower level players, and getting barn cleaned of items not needed, like LEMs, TEMs and other items at the same time.
