It's $800 in most cases, they probably had old forms out.
If though, you were out of the country in December, January, February, And April, and any of those trips were within 30 days of each other then you need to be aware of this (in which case it's only $200):
You have not used your exemption, or any part of it, in the past 30 days. If you use part of your exemption - for example, if you go to England and bring back $150 worth of items - you must wait another 30 days before you are allowed another $800 exemption. (However, see the section on the $200 exemption.)
This is found on the link given above, I wasn't aware that the exemption had a date limit on it until reading a story on exemptions at the end of last year.
