Affiliate and URL problem in Google feed

We are using a plugin for affiliates.  Is there a way to insert a default value in the url string?

I need to have 'a/cd/' inserted after the .biz/ and before the sku, which we use as part of url.


•  I’m concerned about the product URLs in the feed right now. I spot checked one and it returned a “Page Not Found” error. I navigated through the site to find the product & noticed the URL was different:
o  Current value in feed:             https://mebulbs.biz/ll3112
o  Product Page link on site:       https://www.mebulbs.biz/a/cd/ll3112

You can add only suffix for URL (example ?affiliate=1).
and your product URL will have such URL
http://www.foxnetsoft.com/productname?affiliate=1

How do you add suffix?
Open feed and select the second Tab, find the URL tag and press 'Edit'.
