Amazon has the B+W 67mm Clear UV Haze with Multi-Resistant Coating for 42.44
+ FS.
A good filter for lenses such as the Canon kit lenses and Tamron 17-50MM. If
you got yourself a SLR in this holiday season. Invest in a good filter that
will protect your lens.
I also got the free Tiffen filter from Amazon, but trashed them. They cause
ghosting on most of my pics. So a Multi-Resistant Coating filter is a must.
