I've been buying from MercadoLibre for over three years now, and couldn't be more pleased with the selection and the service. I've bought many things through ML, from a refrigerator, to Italian coffee, a lawn swing, antique furniture, and even my new, second-hand puppy....!
ML not only has the best prices, but also a 30-day return policy. If the product is not exactly what was ordered, or there are problems with it, or it was ordered by mistake, ML issues a refund. Had to do it twice, and the refund showed in my account in under a week.
Even with the quarantine in place, there's next day delivery for many items. But if a shipment is delayed, ML notifies the buyer of the new delivery date.
ML, and the Automovil Club Argentino, show how efficient Argentine companies can be.
Too bad there are not more like them.
