Imagine not getting to roleplay shopping because you're a wizard and spent all your money on scribing spells. Imagine thinking that keeps you from roleplaying during anyone else's shopping, assuming that you are also present for the shopping instead of doing something else.

I can't exactly talk though, last session in Curse of Strahd, my character basically turned the session into a heist because he had the best Stealth score and there wasn't enough Invisibility spell for the rest of the party. It's a CoS game, being seen by half the encounters is basically a TPK in and of itself. But he was able to turn what was supposed to be a scouting mission into a successful rescue and robbery, so it was kind of worth it.
