I dont think it would be more than 7.00, if that much? but im still learning all this shipping stuff so ill try to get a more accurate estimate when i make my trip to the post office on wednesday!
To help the winner with shipping you could fit them in a bubble wrap envelope with a flat rate cost, which is much cheaper than any other way. Plus the confirmation number added would only be another .85, So shipping would probably be around 6.00 this way.
Ya, I am new at it too and I almost made the big mistake of having to pay 10.00 just for a tracking number. I called the post office and asked them for the cheapest way and they told me it was bubble wrap envelopes with a confirmation number and you just pay a cheap flat amount. It is parcel post priority mail, that I go with now.
