Anyone who has shopped at Sainsbury’s recently has probably received one of those brand match vouchers. The idea is that Sainsbury’s check the prices of what you have brought against their competitors and if you could have purchased the products cheaper elsewhere they give you a voucher for the difference. That’s all very well but the vouchers have such a limited life, usually only a week that I don’t think I have managed to use one yet. Perhaps I am unusual that I don’t shop every week but I would rather have the discount applied to my current basket.
