Purchase potions with galleons

It would be nice to have the possibility to buy already-finished potions with galleons. While brewing is plenty of fun, the current brewing odds make it somewhat hard to be successful most of the times unfortunately, and the amount of money spent in new ingredients to keep on trying could be instead used to buy the potion itself. There could be restrictions per age/school year (as per the recipes, and the same way it used to work for pets) so that in a way those limitations still apply, and their price could be proportional to their rarity/difficulty to brew. Would just be nice to have the option alongside the current brewing system.

Thank you!
