Sorry I thought you meant you ordered it in a sale and were wondering how long it normally took jessops to deliver

It will probably take at least 2 weeks to deliver the lens.  Have you considered ordering the lens from another site. 

Amazon say it will only take an extra 2 days to deliver the lens and it is the same price as jessops.  If you prefer companies that aren't just online and have shops around the UK then Jacobs have it for the same price and say it will be delivered in 5-7 days. 

When I bought Sigma kit from Clifton Cameras in the past, they just got Sigma to send it direct to me.  I wonder if Jessops operate the same way?  Again, as long as it is in stock it should be pretty fast. 

If you want to buy a camera from Jessops, you may as well walk into the store.  Yes, they take 5-20 minutes of your time inputting your information into the computer system, but it saves waiting for the parcel to arrive.
