Fighting back against supermarkets

It's all too often the case, you've hit the supermarket checkout, stashed all your shopping back in the trolley and away to the carpark battle to escape from the supermarket as quick as you can.

Only once you arrive home, put the shopping away and finally start to recover from the shock of the pricing and battle, does your head start to analyze the visit;
- They don't do a certain product anymore
- They didn't have a product you usually buy
- You used to pay so much for a product, but now you are paying the same price but it's for an own brand version

But one of the most infuriating things for me, is being overcharged by a supermarket!

Considering how everything is computerised and prices are set at the checkout till, it happens more often than not.
In our last 5 visits to asda and tesco (combined) we have been overcharged on 3 occasions!
For the latest, we were overcharged by Tesco.
Running late and in need of a cardigan/jumper for her Christmas party, we slid down the icy hill in the car and nipped into Tesco to see if they had anything.
We paid over the odds for a cardigan, but it did the job.
Off we went to the checkout, producing a huge voucher, for "£5 off clothing when you spend £25 or more instore" (False economy as the prices go up before the voucher is launched I know, so you end up paying the normal price anyway)

We gave the till girl the voucher before she had scanned anything. It was sat on her till in bright green letters.
The next day, I checked the receipt, Tesco's had not put the voucher through the till and now owe us £5!

Add together the time shopping there in the first place, the pricing, no voucher put through the till, the phone call to the store, the return visit (tesco's is not our normal supermarket)... not only has our tesco experience been a poor one, it has actually cost us £5 more than it should have!

"You can visit their website and post this to their feedback website..." I hear you say?
I think not!
Tesco use your information to set pricing against you, exactly the same as asda do when you compare prices through their website (to other supermarkets), but this is for another post.

ALWAYS, when supermarket shopping, check your receipt before leaving the store!
