Where to use BAUCER BUKU 1 Malaysia!... How to use? tips!

Well, i am a university student myself and i have tried several ways to use this baucer buku 1 malaysia in the most effective ways. Some sell it for RM140 and that is what they call it cash rebate.Ok, for university student we cant just go to popular,MHP or some bookstore to just buy books because they aint sell any books for university student,they want us to pre order it. We somehow didn't notice some computer store accept this voucher. Yup, getting a hard disk for storage is a need for student!, headset and so on are need for student.Somehow i still doubt that it can be use, it is so obvious that it mention "baucer buku" so might just stick to BUKU LOL...So what is my intention to blog this topic? i wanted some tips ,some advice on where else i can use it, because the deadline is on march which is just around the corner.WHAT CAN I DO? HELP.. TIPS PLS
