How can an affiliate link directly to a product in our store?
Navigate to Affiliates / Affiliate Name / Affiliate Links / Other URL. Now replace the "EncodedURL" with any product link. Product links can be found at Products / Product Name / Product Link. Be sure to use the encoded version of your product link. This is a good resource - http://www.opinionatedgeek.com/DotNet/Tools/UrlEncode/Encode.aspx.
