Based on the online calculator, I believe it would be $4.95, but I can't say for sure. It shouldn't be much more. I'm sorry to not know for sure, it's my first time trying to ship anything, really.
I don't know if I would be able to do free shipping, because I don't see the bid getting high enough within the 2 hours that are left. :( I'm sorry, I hope this answers your question.
