As of 2012, a coupon book taken to a ration shop provided family minimums for rice, sugar, matches, and oil, to supplement the average wage of $30/month. As of 2019, the fees averaged less than $2 USD for a month of rations, or approximately 12% of their market value, distributes the
libreta to all citizens each year, in the form of a small booklet. This booklet contains pages indicating the exact number and age groups of persons composing the family nucleus (typically, one booklet is released per family nucleus), as well as any dietary indications. A person's products are distributed only at the
bodega that serves their area of official residence. A person cannot receive their products somewhere else, so each change of address requires returning to the OFICODA to update the booklet's data, and those living away from their registered addresses have to return to the previous area for their supplies. Products distributed through the
libreta mechanism are sold at
subsidized prices, which have been kept more or less stable since its inception (the mean salary of a worker has varied very little since, as well). The
libreta contains a page for every month, where the clerk marks what products were withdrawn, and in which quantities. Cubans are required to present the
libreta each time they buy the rations. At its inception, the rationing system included not only food products, but industrial products as well. Along with the
libreta, a tear-off
coupon booklet was distributed, whose purpose was to set the allowances for industrial products, mainly clothing, shoes, and home products, as well as rationing the toys sold to families with children (which were allowed 3 different toys per child per year, usually sold near or on 6 January,
Three Kings Day, or
Día de Reyes). After the demise of the
Eastern Bloc in 1991, Cuba entered the "
Special Period" and industrial products were no longer distributed through this system. A specific set of laws regulate the functioning of the system, as well as establishing penalties for its misuse. Most irregularities deal with clerks not recording products in the booklet, or recording them incorrectly, and the weighing of the products distributed. Citizens could be legally liable if they do not promptly inform the local OFICODA of any changes in the composition of the family nucleus. ==Costs==
