            File.WriteAllText("out1.html", getProductGroupPage.Content.ReadAsStringAsync().Result);

Normally I've tried to mess around the data to see if there was something it wasn't liking but it has all been a waste of time.

I wouldn't post a question like this unless I really spent too much time trying to figure it out. If anyone sees something that I don't see please let me know.

Otherwise there is no errors and the file output at the end for debugging shows the same page reloaded with no changes.
