Interesting comments about 'class'.
I'm reminded that Waitrose promote their Tesco price match on 1,000 products stocked by both (but not promotions). During Tesco's double points promo, I was prompted to comment that the price match meant that WR were 2% more expensive than Tesco allowing for the cash value of Clubcard points.
WR are only 1% more expensive than Tesco on these products now.
