I was browsing around our local Sainsbury's last night and noticed some pc peripherals were on discount at 50%. Items I took note of were....
Saikita white laptop mouse £2.99
Samsung wireless mouse £9.99
Verbatim DVD+/-R 50 pack £8.49
DVD+RW 10 pack £3.99 (could have been CD+RW, cannot recall)
DVD+RW 25 pack £7.99 (could have been CD+RW, cannot recall)
I know some of these items can be found slightly cheaper online, but once you factor in the delivery costs into those prices they will often be the same or slightly more than the prices listed above. A good time to stock up on those DVDs. Items available whilst stocks last.
Have fun shopping!
