On-line purchases by Greek consumers jumped by 30 percent so far this year against 2010, reaching 1.7 billion euros, according to an annual survey by the Athens Economic University's e-Business Research Center (ELTRUN) released on Tuesday.

According to the survey, 1.5 million Greek consumers make an average 15 purchases annually via the Internet, spending some 1.15 million euros, of which two-thirds are made on Greek websites.

The variety and frequency of online purchases increased substantially in 2011, with PCs, electronic goods, travel tickets, hotel bookings, household goods and books continuing to be the best-sellers.

However, the categories with the biggest rises in 2011 were prepared foods, cosmetics/personal care products, jewelry/watches and supermarket products.

There was also a substantial increase in the use and purchase from websites of daily special offers, which accounted for 20 percent of all online purchases in the first half of 2011.
