I'm shocked at how common this has become. It shows such a negligible grasp of human nature. One is simply not going to buy something with a price that is higher than it was yesterday. Especially when it comes to discretionary spending. Haven't they ever gone to a fleamarket where sellers drop their prices the longer you talk to them about an item?
Several of the big online retailers like
Amazon have adopted this very technique though. They've put in place software that, if it detects sales or clicks on a particular item, automatically raises the item's price. For instance, a music CD that attracts interest during a weekend will have a higher price on Monday morning.
I think it's madness. I don't buy things that have a higher price than they did yesterday, even if it's just a few bucks. I feel like I'm being taken for a sucker, and I delete my bookmark of the item.
