I just took over doing the admin for my site a few months back, and up til then, another person was doing the job. They added in BizRate surveys, which have started to annoy customers. Which files are used to generate the receipts?

I've looked in:

orderconfirmation.aspx
receipt.aspx
notification.receipt.xml.config

There's no mention of BizRate in any of these files, but if I pull the code for a receipt, the code is definitely in the bottom of the file. Is there another spot I should look?

The BizRate survey pops up on the receipt, even in the admin, if that makes a difference.
