I don't know if this was a mistake with the barcode in my store only, but I was doing some gift shopping last week and picked up EA Sports Active 2 (Wii fitness game), for my sister. When I scanned it with the scan-as-you-go dubrie it came up £25 instead of £45! Bargain!
If anybody is planning on getting this (for themselves or as a christmas gift for somebody) grab it now and see if it's the same in your store! I'm very happy with that
