...to repeat customers.
Maybe I'm misremembering this, but wasn't there a similar but more scandalous Amazon pricing technique where they were actually tracking customers and jacking up prices to repeat buyers?
Maybe they gave that up due to bad press or maybe they weren't doing it all.
I'm pretty sure airlines have done this -- I've looked at flights a couple of times and when I was ready to book, bam, price had gone up. Checked from another device where I hadn't looked at flights (using a different browser) and I had the original price.
I know Dell did something like this years ago, too -- logged into their site with some corporate credentials and priced a server, did the same thing from another computer/browser which had never used them and the price was a lot lower.
Oh they do. I got one of those push button devices to reorder as it made my first purchase like half price. Normal priced item was around $10, send time around $10, third time it was like $13. Canceled the order and threw the buy now device away. They are getting more and more cheaky about raising prices.
