Was in the Argos in Swiss Cottage yesterday because my boyfriend decides he needs new headphones. He has bought these before and knows they are good quality so got the item number and went to the machines to pay. When he did he was pleasantly surprised to find they'd been reduced!
Argos, in-store catalogue page 436 (i think) are the Sony Fontopia Plus In-Ear Headphones (item number 534/2196) RRP £17.99 when paying at the tills been reduced to £14.23!
Just looked, this deal is online too!
Comes with case for your MP3 player, but unfortunately does no fit iPhones (as my boyfriend found out yesterday)
