Deer were only $150 for non-residents not that long ago. Remember that you can harvest any animal that costs less than the one you have, so if you buy a bear tag you can still shoot a deer on that tag instead of the bear.
Copied this right off the regs.
"A big game locking-tag may be used for a species of equal or lesser value. You must have obtained a harvest ticket or a permit for the other species prior to hunting. For example, if you purchase a $1,000 brown bear locking-tag, but do not take a brown bear, and take a moose instead, you may use the bear locking-tag on the moose, because the moose has a lesser locking-tag value."
