How do you sell tanks in world of tanks?

Answer 1

if you look at the top leftish part of your garauge by the store there is a depot button click that choose your tank and sell. Sometimes your tank will not sell this may be because your barracks are full. There is a box that says sell barracks click it to wear there is NO check in the box then sell.

Selling tanks is also limited to AFAIR 4 or 5 tanks per day.
