hello @dgalan,
one of the things that few people know is that in Venezuela the price of the articles is tied to many factors, for example if a merchant buys a merchandise valued at $100 and then sells it for $120 we would all think that the merchant earned $20.
in venezuela this is not true because there are factors that make the merchants buy a merchandise at 100$ and sell it at 120$ and when they need to replenish inventory the replacement of that inventory will cost them 200$ making the sale a waste of time and money.
