You’d have to check with the UPS and FedEx Web sites to get estimates — their charges are based on the dimensions and weight of the package as well as how far it’s traveling.

USPS rates are based mostly on weight. You can just bring the package in to your local Post Office and they’ll tell you exactly how much it would cost to mail it.

It’s going to cost you several dollars to send, no matter what service you use. Be sure you build in enough postage cost on your auction.

If they dont fit into a manila envelope, I suggest using grocery bag as wrapping paper and sealing tape. You can use plastic instead of paper if it seems lighter but there is a higher price for that kind of packaging.

step 1. wrap it in brown paper, label it.

step 2. go to the post office. (i am assuming you are from the US.) they will have a digital machine that gives you a price for the weight.

step 3. is it less or more then 10.70? (the cost of a medium usps box.) then send it as is. if it is more then pick up a “flat rate medium box” and put in inside.

so the cost will be 10.70 or less.
