Yes, I just bought mine yesterday. You should find them if you enter Anaheim and your dates then search for activities on the left hand side of the page.
OK I took a leap of faith and purchased. And now the fine print said I would get my ticket within 7 days via email. Please tell me it's quicker, we visit in 3 days. yikes!
I also was nervous about it being legit due to the savings but used the LMT tickets at the park last week -- worked perfectly. We received ours via email 2 days after I ordered.
They are legit. If you notice you don't save much if anything for one day, but more the more days you buy. So the prices are frontloaded. The rest is just gravy.
