Just a few weeks ago we saw an unprecedented sale from Best Buy on current generation iMacs and now Amazon has stepped up and surpassed that deal by offering a staggering $150 off 3 out 4 standard configuration iMacs. These super skinny iMacs were released late last year and were in low supply for several months due to high demand. Prices start at just $1,150 for a new 21″ iMac featuring a 2.7GHz quad-core Intel Core i5 processor, 8GB RAM and a 1TB hard drive. Please see other pricing and configurations below. Act fast, Amazon could pull this deal at any time.
