Do you guys notice these just in browsing or do you receive some sort of alerts/notifications from Amazon about sales? I ought to keep tab on these from the US side.
I'm signed up to an Amazon Kindle Daily Deals alert, so I always see the *main* promotions that come up.
However, I also have a Wishlist for any novels I might one day like to buy, and after checking the Daily Deals I then check this list - because often other books will go on sale without ever being notified as such. That how I picked up the Bernard Cornwall novels the other week - there was no notification, I just saw them reduced in my Wishlist.
It only takes a minute each day to run a check, but it's saved me a lot of money. And Kindle Daily Deal alerts have highlighted some books I found too tempting to resist at a steep discount.
