But in DC we have much tighter control over the Forgotten Realms universe.

I tend to agree with you though, except for potions and scrolls, I think there might be a few places selling those, as long as it's only a small number of lower level/weaker items like a potion of cure light wounds. I would think that low level, easily produced items might be in abundance just b/c there are so many people that can make them.
