Look like a reselling website. 14-21 days waiting period look like TS is ordering from online book store and resell it. You can get cheaper (by half including shipping fees) books by buying direct online through the main online book store like Amazon and Bookdepo. The shipping period is less or about the same as TS's store.

For the benefit of LYNers not getting rip off.

Alright, will compare the price around if cheaper then will buy from corak~ If shipping less than 7 days then even better~
