Because you can not put it in an envelope. If it is not a piece of paper, it has to go in a package which costs $1.95 and Listia rules state you must have delivery confirmation (tracking) which costs $.85 for a total of $2.80. Sorry, that's the rules. If I mail it in an envelope for $.45, all you have to do is tell Liistia you did not receive it, and then you could keep it and I would be forced to give you your credits back.
