I know. I bid a lot more than 1, but if no one else bids, it will be worth the $5 shipping. But, just FYI, Listia rules state that you can not charge more than the cost for shipping. But, if I win, I will pay you the $5. But, next time you may want to reconsider so someone doesn't get you kicked off of Listia for not obeying the rules. Good luck.
Since you don't have scales, you could package your items up and take them to the post office and have them weighted there, then list as exact shipping and then when you get the zip code to mail to, you can go to USPS and get a price and you will know exactly what it costs.
