I paid just over £3 for it and P&P was free. And I have to say, I have been impressed so far. My previous case cracked really easily but touch wood, this case has showed no signs of getting up on me yet. The colour along the left hand side has faded a little over time - but for £3 I guess you can kind of expect that.
If you like the pattern, the seller also has cases for other phone models such as the Nokia ASHA 201 and the Xperia J ST26i so they may have one for your phone even if you don't have a relic of a phone like me!
