Maybe I wasn't clear. You have no idea if it "worked" because until you actually try to book, it all looks like everything is going swimmingly. I got the error messages only when I actually tried to book the flights in question. The website was even showing me the discount for flights that didn't qualify, such as flights on CO metal.

Also, it doesn't look like you can stack them
