Stupid Newbie Vendor Question

I'm not quite sure if this is the right forum to ask this, but here goes...

I'm thinking I'd like an in-world store. Rental space has prim limits, though, and I'm assuming (but I could be wrong) that this refers to total prims on location -- so if I've got a 20 prim limit, dropping a box containing a 90 prim necklace is out of the question. I've also sort of gathered that you can use vendors to get around this issue.

However, I don't have land. Are there vendors that will pull objects from my inventory? Free is preferable, but I'm willing to pay.

Thanks.

P.S. I did a search for vendor scripts first, but I didn't trust myself to understand the code.

Actually, the prim limit usually applies to rezed prims. If your 90 prim necklace is in a box, it it doesn't count. Only the box it is in actually counts, which would equal one prim towards your limit.
