I always do my shopping on the Net, all months I do that and buy food, household and another groceries. I buy the flights and the hotels on the Net too for the vacations!!!
I love shopping over the Net, because I don't have a car then it's more comfortable for me, and for the other hand I hate to go shopping.
I like the site of Mercadona's supermarket to buy the food, house hold and some groceries and to buy flights and hotels for a trip I almost always use the edreams.
I can find these kind of materials in English in the library of the course.
