It is the same way here on this side of the big pond. I can order parts in relatively low cost but costs an arm and leg most time to return or when sending them out to others. Sometimes they even want the first born too.
I had brake controller that was shipped in for 4 dollars shipping but cost nearly 20 dollars shipping to return the same defective part. Sometimes it is not even worth the effort to return defective items due to costs.
Personally it looks like China and other big businesses has got the rest of the world by the family jewels. On top of that we the consumers and small businesses end up having make up all that low cost shipping whenever we ship out items.
