4 sets of terms and conditions completed

4 sets of t&c for two different websites.
I have two website. One is an online art gallery the other a craft gallery. I require terms for the both, for customers and sellers/artists and need my current ones editing.

I want to tighten up the art2arts for customer and artist, I do have these written but would like made water tight.

The new site works slightly different in that the customer is buying from the seller and using my site as a platform as apse to art2arts that now operates as selling though me and buying from me.
