What is the delivery charge if you don't mind me asking?
If I worked from home then I'd definitely consider home delivery!
It depends on which day and time you choose - varies from £4 to £6. They guarantee a two-hour slot and deliver evenings or weekends if you're out at work all day. If you want to give it a try I can point you in the direction of a voucher code for money off your first order. If you collect Tesco Clubcard points you can exchange your vouchers for double the value in delivery charge vouchers, effectively giving you double money off your shopping.
Personally I rather like doing my shopping in my dressing gown witha cup of coffee (or glass of wine depending on the time of day) and a cigarette, with not a single screaming child or rude old age pensioner in sight! The only time I go to the supermarket nowadays is if I need cashback or the car needs petrol.
