All information about shipping (admittedly, we're guilty of this too) seems to focus on the biggest countries.
If you are from a smaller country it can in fact be possible that an agent will not offer their services to your country. Another possibility is that the shipping service selection is very small.
Luckily, that's easy to clarify before you even sign up. Just look for a medium sized parcel to your country using the RepArchive Shipping Calculator. It will only return the agents that offer their service to your country. That's it!
