We do most of our shopping in-store, but we occasionally get groceries delivered. I unashamedly use vouchers, and eagerly search out special offers.
For the first time ever I received a call from Ocado this morning, telling me that they noticed we hadn't shopped with them for some time, and asking me if there was any particular reason. When I said that we needed to shop around for lower prices I was immediately offered discount vouchers, and these have just arrived via email.
Times are getting tougher in food retailing.
