Why can you only have 1 hop page? If you have a few domains with different products do you have to make a new account? It doesn't make sense if you're going to be using the same address and personal details.
You can sell various products on the one account, but if you want to run an affiliate program for each product, you will need to set up a different accounts.
Yes, you can use all the same info. The way clickbank is structured, you pretty much need to make a seperate account for each product. There are ways around it, but just make a seperate account and be done with it...that's my advice. Funny how Clickbank doesn't make it easier...but then again, how would they collect that extra $50 per account if they made it easier on us?
When you want to sell something, that is when you get hit with the $50 charge. Another option is to use something like www.easyclickmate.com which will lets you sell multiple products from multiple websites with one clickbank account.
