I usually buy the groceries in the cybersupermarket. It's more comfortable for us because we don't have to carry the heavy items like the potatoes, the milk bottles or the water drums.
I've never bought clothes on the net because I like to try it before but sometimes I have bought flight tickets. This summer, for example, I booked on the net all the hotels of my holidays in the United States. Edreams it's a very good web to make reservations of flights and hotels.
I usually book my theater tickets on the net, too.
