I'm wondering at what point (or poundage) a shipment of computer motherboards, cpus, memory sticks, etc pays a profit above the shipping cost?
For instance, I have about 25 pounds and counting and really would like to try out a small shipment to 1. Obviously make a profit and 2. See how the process works. But I don't want to ship it out too soon and pay more in shipping than I get in profit. I suppose it depends on what exactly is being shipped? Or can you estimate a minumum based on poundage? Any advice, opinions, information? Thanks!
