UK to US rates are much higher. Check out Royal Mail's website and enter a few weights and values and see.
Basically, for a max weight 2kg package with Â£500 insurance to the USA via Royal Mail International Signed For (the cheapest international service with a signature at the other end & insurance), you're looking at about Â£26 ($50-ish).
Courier rates are just insanely expensive from here (try going to Parcelforce's website as an example and entering a few weights & values).
I don't know why shipping from the UK is so pricey, but it is.
Still, as I said earlier, if using Royal Mail ISF, $75 is padding the price a fair bit.
