Lack of delivery slots, difficulty negotiating the sites and an out-of-date pack of sausages marred The Grocer 33’s quarterly online shopping survey this Easter.

Despite vast improvements in stock availability, substitutions and fulfilment compared with our online Easter shop last year, our mystery shoppers gave supermarkets’ online operations a thumbs-down.

“On the whole I was disappointed with the online ordering from Tesco and think it could be organised a little clearer,” said one shopper while another said of Waitrose: “I would not consider using this service again unless there was a free delivery offer.”

The disappointment and frustration cited by the shoppers will be a blow to the supermarkets, which are beginning to crank up their home shopping operations.

Full details in this week’s issue of The Grocer - out Saturday and available from all good newsagents.
