The post you are reporting:
It is always possibleto get a better deal, so the basis of a good deal is that both parties are happy with the terms when they agree to trade. So, Paul, if you thought at the time the Lidl deal was a good one for you, it remains so.
As Ross and Roger suggest, heed Shaw Taylors credo, "keep 'em peeled", as you are then more likley to avoid doing something you regret later, but counterbalance that with paying for cnvenience, fuel savings etc.
Some of the latest Tesco offers also smack of desperation. The gang of 4, Asda, Sainsbury, Morrison, Waitrose, are relentlessly eating away at margins and I suspect it is non-core business that is now making the profits.
