I was at Dollar Tree today and they had autograph books in the school supply section. . .they were quite nice (boys' and girls' styles), and had a plastic spiral bind, but the paper was a bit thin.
I spent a little extra and found Disney autograph and photo albums online. . .i wanted to have them first thing, so i wouldn't be looking for them at the parks. they have room for photos and autographs. I bought these at laughingplace.com. Good prices on most things--still higher than the parks, though.
I boughta few Disney T-shirts at www.mainstreetmegastore.com --which is WAY overpriced for most things, unless you check the clearance section. The t-shirts were park t-shirts, not just disney t-shirts, and very cheap.
You can get autograph books and pressed penny collection books from www.giftsofatime.com, but you will pay a bit more than in the parks and have to pay for shipping.
If you want Disney books, Id just wait and pick them up first thing in one of the parks. I tried ordering one from the online mega store and never received my items. I had ordered it about 2 months before our trip. I checked on the status every day and it never changed (processing order). There was no # to call them, and some of my emails went unanswered. Finally I got an answer which said it would be shipped in 2 weeks. Too late for our trip, so I said to cancel my order and give me a refund. You will pay more for the online shops (shipping and cost to run into the parks to get the items), and sometimes they dont go to the parks everyday or week, so you will have to wait. What you may want to try is the WDW merchandise number. You can tell them what you want and when you need it. I read on here that someone said they had it delivered to their hotel (onsite) and picked them up at check-in. They might ask for a description, so if you can find a picture of what you want, that will help. The one I got is blue and has the characters on it.
