Airfix's Winter Sale ends 27th Jan (tomorrow) at 5pm:
http://www.airfix.com/uk-en/shop/winter-sale/page/2.html?The Shackleton MR.2 is discounted from £45 to £36 amongst other interesting things.
I'd like to get a handful of things, but it's not enough to clear the £30 min order for free shipment. If you're in the same boat, PM me and I'll put a combined order in and we can sort out delivery of your part of it later.
