yes, this seems really too good, but apparently totally legit!
this deal comes from hotukdeals.com
as per subject, your local Sainsburys is selling 120GB XBOX360 Hard Disks for just £48.93
this is an in-store only deal, and it's the original SKU (with disc and transfer cable)
items are not on display, but often in back-room store. So go and be sure to ASK the counter to check availability for you, not just look around... And still if you see any at standard retail price of £129.99 have those price-checked at counter for you. Then you'll see the magic price
cannot verify by myself, of course, but worth a little trip if you have some Sainsburys near you
