M.M.
I would send the stuff. You're not BUYING something you don't need. You're giving people you love things they DO need!
You could shop around for costs -- sometimes UPS is cheaper and sometimes it is the post office. Also the post office has those flat rate boxes that are the same price no matter the weight. You could probably cram the UGGs & Proactive in one of them and the coat in another. I don't know if they go international though.
