The black Fujifilm X-M1 is currently listed by Amazon at £384.62. Although showing as out of stock you can still order it and they will deliver when they get stock. You can then redeem a free 50-203mm lens from Fuji (details below).
**Make sure you do select Amazon as the seller and do not order through a marketplace seller as Fuji will not give you the lens, even if it's fulfilled by Amazon.**
Sliver/brown currently in stock at Amazon but more expensive at £409, which is still historically a good price.
