They’re charging £5 for home grocery deliveries. But the orders, with delivery, are costing £15-20 each to process. And that cost isn’t going to move. But people won’t pay that. They’ll pay £5.
So…Potentailly… if we all decided right now to do all our shopping with Tesco online, we could potentially bankrupt them
The other element of profit that Tesco et al are losing because of online shopping is that people will generally spend less online as they’re not walking around a store putting extra things in their trolley that they didn’t actually go in for.
We always end up spending an extra £20 or so in-store than when we shop online.
Which is why I don’t mind paying £3-£4 delivery, as overall I save (plus it costs me £1.50ish in petrol to get to the supermarket and back).
