UK Grocery Retailers charge for home deliveries usually around 5 pounds per delivery. Some also offer 30 minute delivery windows. This is far too cheap when you consider the cost of paying someone to pick the order, load the van and deliver the goods then you have the cost of fuel and the logistical planning required to hit that 30 minute window.
The only conclusion can be that the web orders are being heavily subsidised by the normal in person customers. If the on-line grocery sales continue to grow at the current rate, in the near future the delivery costs will have to be increased dramatically. Right now you are being seduced with a relatively low cost option, as soon as you have all become too lazy to actually go out of the house (like a true hunter-gatherer) and bring home your own food the supermarkets will all increase their delivery charges to an economically viable level.
