So, my character wants to craft a bag of holding. All construction requirements are met, but the total material components cost for the spell to actually complete crafting process is higher than market cost of this bag. The bag itself on the market costs 2500gp (t2), so crafting cost is 1250gp, but the worst part is the spell "secret chest", which costs 5050gp. So, is it a bug or feature that buying the bag is actually cheaper than craft it?
