Make Money on eBay

Would you rather pay $10 and have free shipping or pay $5 and pay $6 for shipping?  Answer: you prefer the latter.  Well, at least if you are like most bidders on eBay. 

Morgan and co-author Tanjim Hossain, an assistant professor at Hong
Kong University of Science and Technology, held 80 auctions of new
music CDs and Xbox video games to test how consumers respond to
different price schemes. In the eBay study, they varied the opening bid
price and shipping charges on identical CDs, ranging from Britney
Spears to Nirvana, and video games, including Halo and NBA 2K2.

perfectly informed and fully rational consumer will merely add together
the two parts of a price to obtain the total out-of-pocket price for an
item and then decide whether to buy and how much to bid based on this
total price.

But that’s not what happened
in their eBay auctions. Instead, they found that lowering the opening
bid price while raising shipping charges attracts earlier and more
bidders and ultimately leads to higher revenues compared with doing the
reverse. Those findings suggest consumers pay less attention or even
completely overlook shipping costs when making bids…
