The investigation relates in part to the "guide" prices that are
shown on the supermarket web sites. These are necessary because
different local stores have different prices at any one time, but
mean that consumers are sometimes charged more than is actually
shown on-line, according to reports.
Other complaints relate to the inclusion of unsuitable
substitute products for out-of-stock items or the replacement of a
luxury item with a cheaper one, but without a refund of the price
difference.
There are also concerns that some items purchased on-line are
more expensive than those available in-store, and that some orders
sent to consumers include products that are very close to their
sell-by date.
"We have held confidential discussions with the supermarkets.
This is an ongoing investigation," an OFT spokesman told the
Independent newspaper.
Representatives from Asda, Tesco and J Sainsbury's have
confirmed that they have discussed matters with the consumer
watchdog.
Speaking to the BBC, Tesco's corporate affairs director, Lucy
Neville Rolfe denied that on-line consumers were being
overcharged.
"With a Tesco.com grocery shop your food is picked off the
shelves of your local store so whether it is a book you are buying
or a carton of milk, you will be paying the same price as you would
in-store," she said.
