I recently went to eBay to buy some photo paper. While I was waiting for the auction to end, I decided to do a search for everything 50 cents or less with free shipping. Then I bid on several items ending soon. I won eight of them, spending less than two dollars. For less than a quarter each, I got two USB SD card readers, A headphone extension cord, a headphone splitter, and a USB extension cord. Suddenly though, somebody outbid me on my photo paper with six minutes left. So then I bid again with 15 seconds on the clock and won.
I have done these low price bids before, and the interesting thing I have always noticed is that the items often come from Japan, Taiwan, or China. I can understand how that it may be inexpensive to make these products there, but I wonder how 19 cents gives them international shipping and a profit.
