Postage problems

[wallenda]

Maybe I'm missing something...

The most recent  items I have listed I have used "calculated" shipping, put in the weight and measurements of  the box, when it sells the postage due from the buyer always comes out lower than what Ebay is charging me to buy postage and no I have not changed the weight or measurements of the box, it's never alot, $1 or $2 but it adds up

Double check that the ZIP Code in the listing and the "Shipping from" ZIP Code for the label are correct. Sometimes the eBay gremlins change the "Shipping from' ZIP Code so it doesn't match your return address.

You have to remember that eBay charges a final value fee on the shipping and therefore it needs to be included in your shipping charge.  Don't pass on the eBay's shipping discount to the buyer.  Charge the retail rate.  eBay does not discount Media Mail and therefore, you need to add those fees to your item price.
