Scan are based in Bolton, so maybe a 40-60 minutes drive away, so you could maybe save a few quid if you are able to drive over there and pick it up. Maybe not any time soon though beacuse of the state of the roads what with the weather and all
and I know that you said £60, but you can't get new 4GB DDR2 for £60 or under anywhere unless it is maybe B Grade or OEM (same as retail, just less packaging .'. cheaper)
You can always try ebay, £60 is just about the going price for it at the moment and so long as it hasn't been overclocked (manufacturer can't prove it) or overpowered (again, manufacturer can't prove it) it will still have lifetime warranty, so as good as new
