This type of selling, an item for 1c and free shipping seems to me to be a lure by the seller to get emails and addresses of people who will respond to such advertising.
Then perhaps? they can sell such emails and addresses.
The international shipping being put high is perhaps done to block non-US bidders as most people are aware of looking at shipping costs now. (I hope they are.)
It could be some sort of school project also. I have heard of students doing studies of
ebay buyers and listings and seeing what sells compared to what doesn't. Or what gets a response compared to what doesn't. Words used, colours used, prices, shipping amounts, etc, etc. Or just could be a potential
ebay seller inbestigating things himself.
There is always the thought of striking it rich by accident. If you don't play you won't win, the lotto type of thing. Works here in Canada for the Lotto corporations.
I agree the title is misleading, and what most ( I assume) people see is the picture, the title, the price and the seller info. Not too many scroll down and read the description or even pay attention to it if they do.
So what people do is zero in on the emotional words used in the title and they see
Vintage World Stamp
Sale,
huge collection of Postal
Stampseven though the lister could argue that the title can be read as
These are old stamps from around the world.
I am having a sale here.
I have a huge collection of postage stamps.
Because the words are arranged in a non-usual order, people see what they are used to seeing and read it as
Huge Vintage World Collection of Stamps! Sale!
The heart starts racing, you have to get to the finish line before someone else does, you must win the Prize, secure the deal, bring home the bacon, etc.
I think the way to foil such underhandedly human tactics is for one person to bid on all his auctions and win them all, all the time, until the seller tires out. Unless, that is, a computer is listing these oiver and over, which could be the case.
