And yes he should check some tools with abilities and try to cute and paste without buying them, like this "if it work" that mean he stole for free some skills and the shop will remain with ordinary tools !
There is more shops than the one of people he know so he could buy things that help him with alchemy, cooking and others jobs skills, keep the stuff in his bag and only use it alone in the forest or where he sleep...
Also one thing he should try, it's go in a shop that propose storage bag, the best of the best if possible, and try to cut&paste the ability of space storage ! Like if it work he will have another personel bag, even if he only should open it alone !
