Really easy to send a box of my belongings to Spain. It's really difficult in general knowing how to do things post-Brexit, and I did have to pay €30 in customs fees, but in terms of the help Send My Bag give, it was a great service to use and got here much quicker than the expected timeline. Really good experience (it just is a lot of faff now we're not in the EU!).
I sent a snowboard bag plus 2 other boxes and it took 2 days to arrive from a small town in the Austrian alps to Sydney. They quoted 7 days so was shocked how quick it was. Also was the cheapest service from the quotes I requested of several companies. Also the quote is instant which I much preferred!
