Mmmmm......
To qualify you need to buy (for example) 2 x packs of giant choccie buttons = £5.00
You then receive £0.05 per litre off 50 litres of fuel = £2.50
Er.......so my fill up costs me £2.50 more than I would have normally spent.
Or to put it in perspective, £4.00 more than I would spend on my usual Tesco99, that's a 7% premium overall and I end up a fat koont into the bargain.
I know I'm not prone to profane outbursts but scuse my French....Shell can go finger their starfish.
