Fit Flops, saving over £70

Today I looked for some Fit Flops on line, to try and combat the hot weather.  Some I found for £84.99, can you believe that?  I continued searching with the Free app and found various prices starting @ £4.91, £4.99, £7.00, £9.99, £5.99.  By my reckoning which ever ones you choose that's another saving of over £70.  That's Amazing!
