I noticed STAMPS.COM began to charge me 15.99 at this year March. I still remember when I try to use STAMPS.COM, the agent told me STAMPS.COM will no charge me additional fee to use STAMPS.COM, but since this year March, they charged me $15.99. This action is steal, because they never told me they will charge $15.99, furthermore, after the transation, they still want to hide the fact.
