While the whole idea does sound a
little bit on the silly side--kinda Discworld, even--it is extremely interesting, and could fit nicely into certain kinds of non-silly campaigns (particularly ones with a lot of Planescape elements).
I think comparisons between this spell and simply being able to
walk to town and buy what you need are pretty flawed. Obviously, this spell is intended for when access to a normal shop ain't an option. You know: You're stuck in a dungeon with nothing but undead monsters and the gold you stole from them, and you're gonna starve to death before you find your way out. That kind of thing. This spell isn't about merely expediting an action that you could accomplish anyway (buying mundane gear), but about summoning up any of a
very wide array of different items out of nowhere, and expending gold as if it was a material component.
So it's hugely flexible, and could come in extremely handy. Given the inventory restrictions, however, and the fact that you have to pay immediately, this is obviously an
extremely situational spell. It's not something any Wizard will memorize daily unless he's got a
lot of slots of its level available. So, despite the spell's tremendous flexibility, I'm leaning towards 2nd level. Maybe 3rd level, if there was some kind of option to delay payment. ("They took all our money and equipment, but if you sell us a few swords on credit, we can get it all back in an hour.")

Seems like a setting element masquerading as a spell.
I'd give it no level but have it be bought by an action or gift in the game world.
This sounds like a great place for the
Unearthed Arcana incantation rules.
