Parser of all goods from stores on different marketplaces

The first step: the parser takes from the Google table a link to the stores on the market plays (Rozetka, Epicentr, Prom), pars all the goods of the sellers and records in the table the necessary data about the goods.
There are also 3 other sites (shops) for all goods.
The second step: takes from the Google table a link to the goods on different marketplaces and next to record their prices.

Blocking from the markets of plays is the same thought, the mobile proxy is used.
