Site in Portuguese only.
Clube Amostra Grátis—"Free Sample Club", loosely translated—offer consumers an assortment of new products to take home and try before they become available on the shelves. Consumers must first register online and pay a yearly fee of BRL 50. That, in turn, entitles them to visit the store and take home up to five different products each month. Members fill out online surveys about the products they choose, and can also participate in additional activities, including in-store tests, that earn them extra points good towards additional benefits.
Site coded 100% in Yii 1.1, has about 14.000 registered users, and is a conversion of an older crappy Joomla implementation.
