Poundland Selection Packs Bargain

I was in the Metrocentre Poundland today and they were selling off their medium Cadbury's selection packs for 50p each (half price, obviously ). They had previously been on offer at a quid each, or four for £3. I bought four packs today, and the sales assistant had to key each of them manually in as a 50% discount. But when I checked my receipt, the till still takes off a further £1 for buying four.

So my selection packs ended up costing me 25p each. Seems like a reasonable price for five bars of chocolate. :T

I do love Poundland.
