I have being doing ALL my grocery shopping online for years and will never switch back.
I pay 10 a month delivery charges.I can order as many times as I wish per month (including peak time slots) as long as total is over 50.Easily achieved for family of 4.
The delivery slots are 2 hours,so I am homebound for these 2 hours,big deal.
Have trained DS to manage and sign,he doesn't mind as I order him a treat.
Always buy Tesco labelled products,as cheap or cheaper than LIDL/ALDI produce.
A no brainer...funny how women are the most enthusiastic about this practice...I wonder why!
