...The only downside - The Jessops in Dunfermline didn't have in stock, sold out! So they are getting me in one for the 24th...
Just a suggestion: Cancel the Jessops order (£85.49 online even with the CameraLabs voucher) and go to Gordon's Affiliate Stores page
and click on the Amazon.co.uk box. Enter the string "EF 50mm F/1.8" in the search box and you'll see that Amazon have this lens in stock, it's new and is eligible for free delivery and it only costs £66.78. Your choice, of course, but you can save yourself some money and, if you follow the links suggested above rather than going direct to Amazon, you can help support the site.
Blatant commercial plug over!
Wherever you get it have fun with the new lens. I have one (bought via Amazon) and optically it is very good value indeed.
