I've installed MarketPress as a MU installation. I bought a MarketPress licence because I'm *relatively* familiar with WordPress and wanted to make a marketplace store where individual users could create an account and list their products.
The fee model is based on commission: users sign up to list their goods and I take a cut of every sale. Profit! Or so I hoped...
Users are only likely to list a couple of products at a time, so it is going to look very silly if you are forced to go to a number of different minisites when browsing products.
Now, after realising you have to deselect the "global" option in the Network admin to be able to view the commission options, it seems that the torturous process of setting up a PayPal developer account etc. may have been in vain.
Is there some kind of workaround which will enable people visiting the website to be presented with a single store, with contributions from several users, who can all manage only their own products, while I claim commission on every sale? I understand from looking at other people's queries that PayPal limits transactions to five or something, but users are likely to only buy one or two products at a time rather than fill up a basketful.
On a related note, I'm afraid to say it is not proving very intuitive to set up the kind of functionality I require. I'm not sure if there are any better resources available, but a comprehensive user guide to common needs with MarketPress (Etsy store etc.) would be far more helpful, I think, than scrabbling around the forums finding piecemeal bits of info (despite some posts dealing with some issues relatively comprehensively). I only just now received an email from WPMU Dev talking about marvellous Etsy shop-style functionality, but it seems remarkably bothersome to set up...
