Weird one here but I needed to upgrade my SSD in order to run all my VM images from it, I got the Samsung 850 from Amazon France as it was a lot cheaper than here. Turns out there is a cashback deal on but requires a French bank account. I think it's for 50 Euros, seems a shame not to claim it so happy to share it with anyone here who has an account!
Worth keeping an eye on Amazon.fr and Amazon.de if you plan to buy anything with a value of >£100 as the exchange rate is good at the moment and there will be no import duty. In fact it seems a lot of the items actually ship from the UK. The SSD went up in price just after I bought it but the prices are changing daily.
