Selling at trade fairs, exhibitions
A few small exhibitions are being held, yet one of the main problems is that they are not advertised properly.
For example the organizers will announce it only on the day of the exhibition or one day earlier.
Because of the covid-19 pandemic people are going out only once in three days, and they miss the newspaper announcement
The organizers should announce the exhibition at least 4-5 days, so that those who wish to visit can plan their visit in advance.
