I recommend! When you optimize your eBay account, you see increased sales fairly quickly. Thank you for your help!

Anna Płuska

I recommend training on ebay and amazon sales at Mateusz to everyone who is just planning to start selling, as well as to those who want to learn. First of all, it is an amazing dose of knowledge that cannot be read on the Internet, practical exercises and all this in a great atmosphere. I recommend!

Adrian Pakulski

Express help, even after completing the training! The company is definitely worth recommending!

Marek Zieba

Each new platform is a challenge. I recommend eBay implementation training, everything is clear and concrete, thanks to which we saved a lot of time in the company.
