Discount and More Discounts

All the book stores are getting more aggressive on price. Kinokuniya has 20% storewide this weekend. MPH has 20% for 500 titles - not so good deal. I do not know about Times but last weekend, Borders has 25% for 3, 30% for 4 and 35% for 5 books. On top of the 35%, there is an additional 10% for members. Borders has great deals!
