I bought a whitetail tag instead of a regular deer tag; can I exchange them?

I mistakenly had my wife get herself a whitetail only tag when I should have asked her to get a general deer tag. Can she exchange the whitetail tag for a general deer season tag?
Answer: 
Exchanges can be made if the season for the tag you have has not been open.  They can only be done at a Fish and Game office.
