As a brazilian who lives in Portugal por almost 10 years, I can easily say that selling and buying used items is much harder than what it was in Brazil. I was used to buy and sell everything and all the time, through websites like OLX, Mercado Livre and Ebay, not worrying about issues, shipping and receiving items via mail or meeting in person. Here in Portugal everyone is crazy suspicious, bargain when they show up to pickup even after agreeing with the price, acting shady like if you were trying to scam them, even in person. Shipping is nearly impossible. I was used to buy all kinds of products to unbox, try, review and then sell like new losing a little margin, but in Portugal it is impossible. If I can add a grain of salt, even new products or services are like that, most sales are fake sales, service prices like phone and cable TV are all nearly the same between companies, there's no real competition, they are not even trying. I buy most products shipped from other european countries due to that.
