In order to use Amazon Marketplace Webservices (MWS) you will need a Pro Merchant seller account, an Amazon WebStore account, a Checkout by Amazon account, or an Amazon Product Ads account. The Pro Merchant or Professional Sellers account is currently priced at £25.00 or $39.99 USD per month. Then sign up for MWS by clicking the Sign up for MWS button at http://developer.amazonservices.co.uk/ (or appropriate for your region).

If done right, using above APIs can completely automate the process of creating new products on Amazon, linking your data to existing products (by linking to the same ASINs, EANs, UPCs or ISBNs) as well as changing images, prices and inventory.
The Amazon Developer site has C# sample client code for you to play with. Other useful references:
