Yes you can
My wife and I just went last week. It has slightly changed then a few months ago. Yes, you are able to get everything at once and up until 30 min before your movie ends. We found that unless you are getting hot food or a lot of stuff it is cheaper to simply pay for the drinks and popcorn bundles. It is $15.70 a person for the all inclusive that you pay on top of your tickets. The pricing that way hasn't really changed. You just cannot buy at website now. Still a good deal if you are eating there, or if one person gets the all inclusive and comes back before movie starts to get more snacks.
Why pay more money to get hot food? Stupid if you ask me
