Carlos thinks he found a unique market opportunity! One week ago he went to El Corte Ingles and focused on the surprising offers of -70% on the second item; or 2 for the price of 1. He figured that some of these offers are intended to attract customers getting inside the shop. He figured that if he could buy all bargains at 70% or more; and offer them through an on-line platform at 50% he could pocket the 20% margin. He would focus on small batches to avoid being left with any stock. Assess the business idea
