I bought a large one at Burlington Coat Factory for 49.99, they had a large selection as well. However, the coating / color has started to peel and fade off in some areas of the bag and I only bought it in August.
We have them at Gordman's here in Iowa. Under $45 and they are excellent. My fav one is over 2 years old and still looks new! You can also get them at Dillards and Younkers, but a lot more expensive.
TJMaxx and check Wilson's leather online. They always have Kathy purses on clearance and sometimes they have an extra % off clearance special going. I got my dd a beautiful bag a couple years ago for under $20!
