I'm not sure what to say about it, yet. Where I am the market isn't really developing, and the materials for the potions can be relatively expensive, therefore the cost of the potion is relatively expensive. There's also the additional problem of inventory slots being taken up by situational items, and many players already have inventory issues.

If people use these items sparingly, it's going to be very easy for the market to get saturated, if any market for these items does appear.
