if you are taking paypal payment, you can even pay thru that for shipping and it would be even cheaper than post office. you just type in how much it weighs and choose media mail thru usps... it was only $3 for my to ship 3 lbs that way of movies. researching i found out a VHS tape weighs about 7 ounces each so 22 tapes would be 9.6 lbs so i would just say its at 10 lbs. so media mail for your auction SHOULD be $6
they dont have fees for shipping. just in accepting payments. and you can ask the person to send payment as a gift or payment owed and then you wouldnt have to pay ANY fees! :) i'd be happy to do that caz i'm fully intending to try winning this auction for my son :)
