Because it is just a dream.. is time to wake up.
Never sign anything on those expo as they are working on commission and also need to pay for the rental. So they will do anything to make you sign in. Sales convincing power.
Better walk into the shop and ask for package. But I think is too late for you.
For others, I would recommend Monliza, below 5k package, got everything you have and have even more like special theme dress.
