I’ve thought about going back through all of my sheet’s revisions and seeing if there were any pattern to the prices, but that will take some work and I just haven’t had the time.
From my general feeling after updating this sheet for 18 months or more: Most of the time the prices for each vendor tend to swing up and down only a few dollars over the course of a month or two.
Not sure if it is their supply/demand or just trying to out-maneuver each other. (Probably both.)
Once in a while there is a special sale that can pop up, but they are few and far between. Last year or so was one from UT where they got hold of a bunch of older non-expire tickets and sold them at a super discount. But, that only lasted a day or so before they sold out.
If you keep an eye on the TP chat, usually one of us will post a message if something good appears. Alsom sign up for the resellers’ mailing lists if they have one.
When I bought ours for our August trip last year I held out until my FPP day arrived and then bought the tix. IMHO doesn’t hurt to wait at this point unless Disney is planning a mid-year increase (which may happen if they start tiering all of the tickets), but that’s speculation.
And usually the resellers have a lag time where their prices don’t jump up until a week or more after Disney jumps.
This is a whole different animal than just finding good ticket prices, but if you haven’t looked into it already, you can try to save more money by using credit card travel reimbursements -
I wrote a whole post on using BarclayCard sign on bonus rewards to get $1200 in savings for our tickets last year. The good news is that Undercover Tourist tickets code as travel and you can use the reimbursements on them.
