I just noticed USA wasn't on that list, was it?. Sorry about that. It was sent to me by a Canadian and all he said at the start of the e-mail (21 June) was:

"Today, In Saskatchean, about 1.20/litre which is about 5.00/g"

Didn't mean a lot to me, so I didn't copy it to the thread. US5 a gallon? Yes, probably that's it.
