Very nice! Couple of questions if you could answer please. How do you host your site? How do you compare the similar products and aggregate them within your database? Unique identifies etc.
> How do you host your site?
TL;DR: entry level Virtual Private Server (VPS) per country.
Based on some SEO articles, I decided to go for Top Level Domains depending on target market (.es for Spain, .de for Germany, etc.) so I needed properly geolocated IP addresses for each country. Each server is around 10 USD/month making this approach affordable. I do all operations.

Each product is manually added (using self made web based template) into database basically because of custom description, picture and specifications. Similar products are linked based first on category and then using properties like weight and drop.
