That is what has me leaning towards just buying directly through Disney just in case something came up and we had to postpone our trip we would still have valid tickets paid for that can be used at a later date.
If there wasn't a date restriction on this deal I would be all over it.
You can still get the same price discounted tickets through Undercover Tourist/Mousesavers discount and save the $27 over disney price. they have no restrictions. You just won't get the 10% back
