Right now, postage for 10x 5x5cm or 10x10cm boards from China seems to be averaging $20 to $30, regardless of the low prices of the boards themselves. Are there houses and/or creative ordering techniques (only get 5 boards to reduce weight?) that cut down on total cost for small quantity hobbyist projects? (I guess at 5x5cm, OSHPark gets you 3 boards for only $20 TOTAL, which is pretty good if you only want 3 boards...)
