Where can you buy bulk goods for cheap?

I visited the Mayorista store today to buy candy/sweets for some upcoming Birthday parties.  The store is a very basic warehouse style store of bulk buy goods.  The pictured lollipops were only $38 pesos for a bag of 50!  the pictured hard sweets were $145 pesos for a bag of 135.  I was pretty happy with the prices.  Worth checking out if you like buying in bulk :)

Mayorista:  Km 20.800 Avenida Giannatasio, Canelones  - 2682 8304
