Convenient search by technical specifications, a large selection of products. You can read reviews not only for the selected product, but also for the store where you decided to make a purchase.
I left a negative review on the catalog website for the store, which tried to cheat in the price when accepting an order. The review was deleted, only excellent reviews remained on the store, which misleads customers about the store's reputation. Who is misleading customers? That's right - 1 directory.
