Selection of winners
Are there any requirements for the selection of winners and award of prizes?

Argentina
The terms and conditions of the promotion must be made available to the public and the process through which the winners shall be determined needs to be clearly established, including dates and place where the process will take place. It is suggested that the process be supervised by a Notary Public.
If the awards are to be determined by chance, the mathematic adjudication used to determine the winner needs to be provided; if this is not possible, an approximate estimation of it needs to be provided.
The names of the winners shall be published within ten (10) days, counted from the end of the promotion, by the same media used to promote the contest/promotion.
The terms and conditions should indicate date and place where the prizes will be delivered.
