Ellis Brigham have a proper sale on this time due to a big refit. Not their usual "5% off left-handed corkscrews" or, "buy one 1996 season snowboard, get the second 20% off" crap.
Proper 50% off respectable £200-450 rain jackets/shells by Mountain Equipment and TNF Summit Series stuff etc.
Also, Trepass have a proper 50% off everything in the whole shop sale on. I like a lot of their own brand stuff and at that price a lot of it's a steal. My old gaiters are shot - replaced for £9, and some waterproof all-in-one's for Stoner Jr's for £8 each. inexpensive approach shoes for £20 etc. Unfortunately I cant fit into their size 12s so beware they come up small.
Im all sorted for most outer wear already, unfortunately, so couldnt fill my boots, but you might.
