I have used this a number of times and always had my results back the next day.
On Sunday I purchased 2 ambi pur refills from Tesco at 2 for £7. They are 2 for £6 in Asda, so I was expecting my results to say that they would give £2 as in their double the difference promise.
Had to submit my receipt details twice which was slightly suspicious.
Had my results back today and apparently only one refill is comparable, even though both refills are available on Asda's site. So the comparable refill was £3.50 at Tesco and £4.67 at Asda. Making my shop "cheaper" at Tesco.
They are obviously trying to worm their way out of giving me a voucher for double the difference. Think it's a bit of a cheek really!
Anyone had any problems with Tesco price check before?
