Hi, I plan to goto Hatyai in nov with my friends. I have asked around, they suggest we take the bus ekspress from Puduraya to Hatyai. My question are :

1) The journey is ard 13 hours from KL- Hatyai?
2) Coz we are planning to goto hatyai for shopping . eg. household stuff (zebra brand), towel and etc . It is really can get a very cheap price compare with KL's price?
3) If I buy few zebra's pot/ wok, what is the tax look like? very expensive?

Thanks
