Ok, I'll start at the begining. I needed to purchase some Blank Sony Minidiscs. Asda had the best deal listed on their website. 5 disc & a 10 disc case for £4.88. Whilst looking through the other makes etc I noticed just plain old boxes of 10 discs for £8.88 reduced from £9.97 so I took a box of them too. With my bit's & bob's I estimated the bill to be about £25.00 the lady asked for £15.76.
I checked the receipt & sure enough the box of ten had been sold to me for 1p, I got two more boxes from the shelf and went back to the checkout & told the lady I would purchase all the boxes if they were selling them at this price. She scanned them & they came up at 1p each box and she summoned the supervisor whom replied they have been reduced as they are discontinued, true to my word I bought them all.
