Massive jump in price for GSP orders to the USA (from UK)

[sly_raise]

Is anyone aware why global shipping scheme orders have suddenly jumped drastically in price for orders to the USA (from the UK?) A seller just informed me he’s being quoted $117 for a t shirt and another buyer cancelled an order and I can see they were refunded £129 for a £26 pounds order! Is this is a glitch or is something else going on?

This is why I was so against switching to using royal mail myself. Years back I paid them for tracked & Signed yet they failed to not only get signature in USA but to even claim delivered. Luckily buyer never pulled a fast one. But they never left feedback either which I have found now even shipping GSP none ( except 1 kind lady) Ever leave feedback. This means if I Hadn't Used GSP I could've been waiting 3months to get paid. I've now clicked to close account anyway. Too many problems since gsp price hike to usa, then simple delivery & nxt apparently new payment policies. Its ruined any chance of selling
