9. Results The main percentage of the sites include offers about beauty care, spas, travelling and food Much fewer percentage of them offers deals about education or cultural events Most of the sites provide deals in Athens, fewer in Thessaloniki and almost 50% in other cities Most of the sites allow their clients to use credit cards at their transactions. Few of them allow using bank deposit while only 40% accept the usage of Paypal Only a small percentage reward their customers for inviting friends

10. Results Using regression analysis, it has been identified that: Maximum discount and Alexa Greek rank are associated with each other at a great extend The analysis of the remaining pairs of variables by using linear regression, does not indicate any significant relationship between them, although according to common sense, there should be a certain correlation.
