£1.89/l in Suffolk
At current exchange rates and for the OP in Alaska, that's $11.23 USD/USG in Suffolk UK, and $9.98 USD/USG in Shropshire UK.
(The Suffolk figure is 2.5 times today's price at my local mainland US airport - the local price is dropping like a rock these days. The Alaskan price is higher, presumably due to the distribution cost)
