Apparently, you misunderstood me. I meant that postage stamp sellers sometimes overestimate, or underestimate the price requirement. Some want $ 5.50 for this series with canceled stamps, the other wants $ 4.50 for a series with canceled stamps. And, having indicated the price, I do not want to be incorrect, it is easier to say that demand dictates supply))
