I have a Tesco delivery every 5 weeks. I use it for all the heavy/bulky items that I struggle to lift now, such as fizzy pop and cat litter.
Tesco have a limit of 5 bags of cat litter per order, this is why I order every 5 weeks
My OH only drinks fizzy pop, and goes through 4 bottles a week, therefore 20 bottles per order
I also add bulky items like toilet/kitchen rolls, and washing liquid.
I have no bother making the £50 minimum spend limit, but recently discovered that if my order is missing some items because Tesco is out of stock, causing the total to fall below £50 ( ie not my fault), I got charged £5 for delivery! I complained immediately to Tesco head office, and was reimbursed, but it is something to be aware of.
Take care xx
