Amazon is selling the Art of Electronics, 3rd ed, for $59.96, eligible for Prime free shipping. Hah, that's
50% of list, and about $12 less than the wholesale price, so they appear to be selling it at a loss. I ordered a copy last week and it was the 10th printing in perfect condition. This printing has been updated and is virtually free from errors. (Note, it was a genuine*** book, printed by Cambridge University Press in the US.)They only let you order one copy, then you're locked from ordering any more directly from Amazon at that price. You also can't get more from them at a higher price (you can select "Other Sellers", higher prices). There's no saying how long they'll continue with this remarkable price; a short while ago they were selling it for $96 each. Hah, this low price has improved the Amazon Best Sellers Rank to #4,803 in all Books.
[*** As opposed one of the several low-cost Indian or Malaysian fake counterfeits, sold on Amazon at low prices. These were copied from a 1st-printing (with its errors, sorry), and they have horrible binding, binding spline page alignment, poor printing, faded photos, stuck pages, and several other serious flaws to spoil your experience.]
