In a different thread, there was a discussion on a certain sale from Amazon. There were those who said it was a tremendous deal, (92% off the list price,) while others argued that if it was so cheap, then there had to be some issue with it. The rating system on Amazon was not very helpful being that there were only 4 reviews. So the conversation about sorta just fizzled out, with the only thing being known about it was that one guy said his wife liked it and another guy accused him of adverting the book for his relative
.
We also know, that every year, when Black Friday and Cyber Monday comes around, the stores are very often just getting rid of old stock or items that didn't sell well. That could mean many different things, the two main ones being that a) the item was too expensive but with the sale it's actually a good price, or b) its a bad item.
We also know that if its too good to be true, its probably not (except if its a mistake or for advertisement).
So the question for the "DDO" (Dan's Deal's Oilum) is; when is a sale a good deal and when is it, well, a sort of scam?
Of course, if you were planning to get it anyway, then its great. But we are talking about how to know if the sale is inherently good or not.
Please share your wisdom and knowledge about this.
