To move household goods is worth in many ways, specially because you could bring stuff like electronics and appliances that is cheaper in Ecuador.
There are some other items that you won’t find in Ecuador or that their prices are too high here, for example items like good mattresses (specially for back pain), good pillows, cash iron are not easy to find here either, the prices of stainless steel pots are expensive ...
Other items like generators, big TVs 60", ziplog bags, good heaters or air conditioners, computers, refrigerators, stove, washer, dryer, dishwasher, stereos & electronics in general are cheaper in USA, Canada and other countries than in Ecuador, the reason is because we import them and importers must pay high taxes to import them..
You have to be aware and bring brands like Sony, Panasonic, Lg, Samsung, Whirpool, JVC that have spare parts.
There are tools for different fields that in Ecuador are not available or are too expensive, especially for carpenter activity.
Only the difference in prices in above items would pay a good portion of your shipment.
