I ordered a Sigma lens from Jessops on 19th January. I've not heard a peep since. It's lucky I'm in no rush.
Eeek! The price has risen from £379 to £599, at Jessops, since I ordered. If they don't honour the original price I think I'll manage without it. The best price today on Camerapricebuster is £557. I'm not paying that either.
