Integrating Zen Cart and Ebay for payments

Hi all, I'd like to be able to integrate Zen Cart with ebay so that I can allow my ebay customers to pay through my merchant account so I don't get stung with as many paypal fees!

I've spoken to ebay and they say that it's permitted c/o a european law allowing 3rd party carts/ payment providers to be integrated into the checkout process.

I've spoken to the company whom I'm looking to use for supplying and setting up my ecommerce payment solution and also sagepay who actually process the payments and they both say that it's the shopping cart that gets integrate rather than anything they provide.

I've already got a Zen Cart shop (latest version) set up and functioning with paypal. I've also got a well established ebay business again with paypal.

Am I asking too much of Zen Cart or have I just not looked in the right places yet???

Thanks in advance

Andy

Isnt your payment processor going to sting you for a couple of percent anyway? Is it worth the bother? Customers on Ebay like using Paypal, and you can bet 99.99% of users have an account.
