i've just been into the Manchester Arndale Virgin Mobile store and they currently have the LG Shine at £79.99 on their weekend special from Boxing day until the 30th. This offer is only available in store and not online.
They have also launched their sale on numerous handsets including the Nokia 1112/2310/7373/N73/N95, Samsung D900i/M300, SE K510i/K800i. These handsets are all 25% off and start from as little as £11. I would hurry into store whilst stocks last.
