YAHOO merchant account, plz help

[Visual Basic.Net]

hi. I need to open my online store to sell my scripts and applications. I want to allow the purchasers to download the program they purchased. I searched for the proper script and i found www.oscommerce.com. It contains all features that I need. but the problem now with the merchant account to accept Visa and master cards...etc I searched alot for some sites offer it for outside america. I didn't found any else than Yahoo:
http://smallbusiness.yahoo.com/ecommerce/

My Questions:
1) what is required to open my own merchant account in yahoo ?
2) How much money I have to pay, to create the whole site with merchant...etc ?
3) Is yahoo plan allow me to use OSCommerce instead of their own ready software? Is their software allow users to download the items that they purchased?
4) How I get my money? where are they going when some one purchased from my site?

Thank's in advance

I believe Yahoo Commerce is something like a competitor to OSCommerce. Yahoo Commerce lets you use their services for the actual purchase while your site can have static pages that simply link to Yahoo Commerce pages.

OSCommerce is a full site meant for showcasing your product and performing the purchase on one server.

So I suppose the answers to your questions depend on what path you will choose (you can't use OSCommerce on Yahoo's Merchant websites, it defeats their purpose)

So, the script provided by yahoo with their merchant accounts are capable of selling virual (downlodable) products?
I hope somebody answer my above questions
Thank's
