I'm afraid I have no help to offer Joseph, but I've had an equally frustrating experience:
First I got a 50% off offer on my cell phone, but I couldn't access the offer. The green button is cut off on my screen. There's nothing to click.
Then I got a 40% off offer (also on my phone). I thought I had taken advantage of it, but evidently not. I can't get back to that offer.
I decided to go to my PC. There were no offers initially, but a 25% offer eventually popped up.
Why can't I get back to the 40% off offer. Why are there different offers on different devices?
