2 promotional code that is necessary to register on the website to participate in some lottery or receive other bonuses.
The first promo code — in advertising, the second "under the cap" (even enough promupakovka). So you will be able to estimate the number of people who bought the product after viewing the advertisement (of course, not all who after buy — will still register the promo codes, so registered must still be multiplied by a factor k).
It is rather for FMCG and not for retela. - holden commented on June 5th 19 at 22:02
