1. boxes are safest to transport electronics. even boxes of boxes. imagine someone will jump over the package. bags are not good :-)
2. you can mark shipment a "gift: old collectioner electronics boards" and value $10 total it will be the tax free at the risk of loosing everything valuable (maybe some insurance is possible but then real value must be known and provided). 3. maybe cheapest local delivery of all bundle to Brazil/ USA, then local arrangement + redistribution would be least painful logistics? 4. for international delivery FedEx is the best as they calculate all taxes and customs upon order so there are no additional expenses and surprises upon delivery (tested with USA Taiwan Singapore Europe UK). -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
