Philips DVD Recorder £39.99.................

Or so I thought..................

I went into the Oxford branch of Argos this evening, and on a shelf with a great big official Argos sign read "Philips DVD recorder £39.99". So, I picked up one of the boxes under the sign, which was a philips dvd recorder. I took it to the checkout and the price came up at £149.99. Obviously I was not happy and asked to speak to the Manager, about 10 minuites later she appeared and informed me, that last night one of the lads printed out a wrong ticket and this was not the correct price. I argued the point, but she would not lower the price, stating that she was withdrawing it from sale................Is this correct
Any advice

Thanks
