Is it from a seller you've already purchased from? 

There are limits on new buyers; sometimes across the board; sometimes by a particular seller.

All new buyers have spending limits until they are proven to be trustworthy, this is nothing personal . You need to buy some lower priced items, pay immediately and leave feedback for your sellers. Perhaps you have a friend who has a good track record with eBay, and would be willing to purchase the item for you from their account.
