I haven't tried online shopping before, but I've heard you can really save more if you choose to buy some stuff online that buying them here.
The only problem is the shipping, and of course, the shipping fees. If you're just trying to buy a book, then the shipping fees would probably be higher than your book's costs. Haha. You better just request for it from Fully Booked, then. :) Yep, Fully Booked. Still the best book store in the country for me. :)
