^ Nevermind, I think I was looking at the wrong one (the one I was looking at sold 111 over the past weekend for $1.99, is $69.99 now, but the store has nearly 30k FB). 

I don't know if it was the case this time. But, I have noticed that a lot of sellers start out a listing very very cheap and the put the price up after a few sales.

 

I believe they do this for two reasons.

 

Firstly, and most obviously, to gauge the market to see how much they can sell it for.

 

But most importantly to get some "sales history". Once they've got the sales history and have got their listing to the top of best match rankings, then they put up the price. It's actually a very smart tactic if you are planning to sell hundreds of the same item.

 

However, the difference in prices of your item shows it most probably was an error.

 

In relation to sending more money, I wouldn't worry about it. If they have sold 140 at that price they've had plenty of time to wake up if it was a mistake, and as you said, you only bought it because it was cheap.

Shows how important a well-thought out listing is to sales 🙂

 

I bought a TV from eBay, the price has been all over the place since it was originally listed. That appears intentional. Major retailer, and the eBay price can vary a lot from their official online store price. Hundreds less, here.

Modestbods:
" If however it was an advertising/promo deal, then for a large store/brand it may not have been all that expensive (especially given their actual manufacture/wholesale costs would have been far less than their normal selling price)."

It does sound like that could be the case, especially as the ebay store was new. Item could cost them $10 to buy. Wallets used as loss leaders.
