You can have several IDs, each one needs (as said above) it's own separate email. The rest of the details can be the same.

one thing not mentioned yet is that eBay will know which IDs are yours, of course, and to sell on any of them all have to be "in good standing".

That basically means if you have any defects etc. come through that limit selling, on one ID, you can't then use a different ID to get around it ... any limits apply equally to all IDs held by the one person.

Not anticipating any bad stuff, just so you know 🙂
