Hello: I made an attempt to request the author copies from Amazon, and I realized they do charge shipping costs, because the weight of the shipment would be too high. So, the US$1,000 would allow me to bring 168 books, approximately. I would still be needing to deduct from that amount the commissions PayPal charges (which has been a different percentage in each donation), the commission GoGetFunding charges (4% of the amount donated) and the commission Banco Nacional will charge (US$11, fixed) to bring the money to my bank account. Let's keep our fingers crossed. :)
