The following code, when provided with the urls of some products in Skroutz, selects those shops that will result in the minimum cost.

Notes:

1. The file containing the urls should be named 'product_urls.txt'
2. The results are printed in a .csv file
3. The website Skroutz.gr updates its UI regurarly, so in case the code does not work modifications in the xpath are required (look class_shop.py).
