Alibris sale - NOT amateur radio

At one time I used to get emails telling me about Alibris sales every week. Yesterday I had one offering £20 off for one day only. It was deleted. I have a filter to get rid of these.

Alibris: yet another "sale" - NOT amateur radio

Alibris, the book seller on line, is having yet another "sale". Hardly a week passes without one. Anyone who buys from them outside a "sale" must be stupid. As a marketing technique they need to see a psychiatrist as few now believe their "sales".
