Just a short post today. I've noticed recently that while none of the other supermarkets do this, Sainsbury's prints its receipts on double sided paper (thus halving its use of this material). Waitrose is particularly terrible at this aspect of the business (which is surprising given they present themselves as a leader on the green side of things) - I bought one thing the other day and I had to fold the receipt before it would go in my wallet! Why can't anyone see that small changes are just as important as paradigm shifts?
