What to pay - Bumbo Seat

I paid $13 for my bumbo seat. (I talked her down from $15) and it came with the box (better resale?). I also purchased one for $10 for a friend (talked down from $15 as well).

They are $40 at babies R us.

Has anyone else seen many more blue seats out there than any other color? 
Do you have a bumbo? 
How much/long did you use it? 
Did you get a good deal? 
When shopping for used things, would you be more willing to purchase something in its original packaging?
