Hi..my sister did that once, and had to have hers shipped back to her house...I would send them UPS, and make sure they are very 'comfy' in whatever box you use...use bubble wrap, or and old t shirt, or any old fabric....anything to keep them from moving around in the box. I don't care for the USPS any longer, they are very unprofessional, very incompetent, in my opinion, they lose things way too often.
