We use Tesco to deliver our groceries every week and they’ve always come through! If they don’t have what we want, they substitute our items for something better and then refund us the difference to boot! They always carry the crates of groceries into the kitchen too, which is pretty nice. Prices are pretty good as is the selection. We used to use ASDA to deliver to us, but they were never dependable, let us down constantly, sometime’s refused to carry in the groceries and gave us weird substitutes. Ocado was very dependable, but is very expensive and quality isn’t that great compared to any other place. Tesco has always been great though, so an A+ from me!
