The second chance is with "Cyber Monday" which is the day after tomorrow.
That's the online version of Black Friday, so you never know, there may be a lot more deals then, or we may end up all having to do as Andy did and order stuff straight from the US.
I've done it before myself actually, and assuming you can get past the different voltages and plugs etc by one means or another then, even including shipping and tax, many things are a lot cheaper straight from the US. My bargain was a Worksharp WS3000 sharpener from Darex. The only place to buy them in the UK is Rutlands, who sells it currently at £230 odds. I got mine, including extras, tax, duty and postage, for about £180 at the time. As it was it didn't work out, there was a fault and Amazon refunded the postage, duty and tax for me very easily when I returned it - so all in all a pretty positive experience even if I did end up buying locally in the end.
I believe (I'm not certain it's true- maybe someone can verify for me) that if your order is under £50 then there's no tax or duty levied anyway?
Here's hoping.
