I have bought training courses for Wildberries multiple times, and I always encountered complete nonsense. I am very happy to have found the Marpla school; many aspects became clear almost immediately, and I developed a correct understanding of how to work and set up processes. It was especially important to figure out the calculation of units and overall product turnover, as well as advertising setup. Meetings with mentors are a separate topic; they are the most experienced and the best. Now it's only forward with such knowledge!
