Rospotrabendzor identified the price tag of only 100 grams as a violation. A Picbo user decided to buy a 390g box of cookies from Pietrochka. The price tag of this product indicated a price of 39.99 rubles per 100 grams, which is only an approximate fraction of the cost. At the same time, the mandatory information about the final cost of a product unit (complete package) is completely absent from the price tag, as well as the price per 1 kg. As a result of a lack of information about the cost of the goods at the checkout, a package of cookies was sold at a price unknown to the buyer - 156.00 rubles per package (based on a cost of 399.99 rubles per kg and a weight of 0.390 kg). The author of the story considered this a violation because: according to Article 3 of the Rules for the Sale of Goods (Decision of the Government of the Russian Federation No. 2463) and Art. Section 10 of the "Protection of Consumer Rights" law requires the seller to indicate the price per unit of goods. For piece products in original packaging, this is the cost of the entire package; Specifying the price only for 100 grams hides the final cost of the product, prevents the buyer from knowing this in advance and may mislead him. The author sent his arguments to Rospotrabendzor. This is how the department responded to him: products in factory packaging cannot be distributed. The agency clearly stated: since the product is packaged by the manufacturer, has a fixed weight, and the buyer cannot pour himself a portion in the hall, this product is intended for sale as a whole only. This is a violation of the law. Rospotrabendzor admitted that specifying the price per 100 grams per piece of product "creates unreasonable difficulties in understanding the price", requires the buyer to perform additional calculations and violates Art. 8 and art. 10 of the Law "Protection of Consumer Rights". The seller is obliged to indicate the actual cost of a unit (piece) of goods. Cost per 100 grams can be used in addition, for example, to compare products of different weights, but should not replace the final price.
