In the midst of a move from Switzerland to Mongolia, I realized than an extra 30 kilo bag on the airplane was going to cost me an additional $800. I found SendMyBag online and used their services, which saved me almost half. The only downside was having to wait all day for the DHL driver, but I had been warned about this in advance.
I had looked into other ways of sending a box to my daughter in Australia but this was so easy, box collected and delivered one week later. Customer service excellent as had questions on customs forms that were all answered by return, very impressed.
I lived in Berlin for a few months and was very stressed about how I was going to get everything home. Send My Bag made this process so painless, everything arrived in great condition and their customer service is great. I wouldn't hesitate to recommend them for anyone who has too much stuff they don't want to stress with at the airport!
