I ordered two Christmas shower curtains on 11/13/16. I received one of them today. Not sure why they didn't ship together. Anyway the second one shows it being delivered by China surface mail? I live in the USA. What is China surface mail? Last thing the tracking showed was for 12/4/16. Nothing since. When can I expect it to get here? It won't do me much good if it gets her after Christmas. Tracking number is BJ14806404499122
