I called the company. The estimated price for a package of 10 binders for 8X8 scrapbooks is $65, about $6.50 per book. That was the price he gave me when I asked about the binder with the most pages. (One website says the binders can hold up to 55 pages!) They do come in other colors besides white and black. He mentioned leather, burgundy, and navy.
The Unibind person said that the Creator is only available online and they are seIling like hot cakes. I checked Best Buy online and they advertise the Creator for $99, but they are out of stock. Target online wants $129, so I guess I will wait.
