Procon OÜ develops and constructs  an automatic retail sale network in co-operation with NRG Box OÜ,  which enables it to sell packaged bulk substances and other various  other packaged products (fuel pellets, grill coal, cat litter, fuel briquettes, firewood, etc.) 24/7 in a fully-automatic mode and without the need for personnel   .

For companies looking to sell their goods via the automatic retail sale network, NRG Box automatic retail network gives independence from large trade chains, from mark-ups of mediators as well as from the working hours of fuel centres. It is possible to place the containers of the retail sale network exactly in the location where the turnover of the offered goods is highest.
