w*******y 发帖数: 60932 | 1 Entertainment.com is running a 30% off sale on their books, as mentioned
elsewhere. Today only e-b-a-t-e-s has 50% cashback at entertainment.com. So
the math is: (100%-30%)/50% is 35% of original cost, or 65% off. Shipping is
free.
In addtion, you can buy an unlimited (?) set of additional books for $20,
which will be $10 after cashback.
