Totally opposite. GSP rates from the US to UK were
crazy cheap.
I sold a bunch of items. Compared to USPS rates they were 1/3 often.
Again I am talking about getting stuff from the UK to the US. Generally speaking it seems
like shipping from the US to anywhere (except maybe China) is cheaper than the opposite
direction. I.e. for me to ship to Canada, Australia, Europe generally is much cheaper than
if I was to buy the same item and have them ship it to me from those destinations. YMMV.
