Shops in bangkok

I used to be a regular in many outlets in and around BKK. Steelbooks are hyper expensive tho. They also have the nasty habit of upping the prices if they feel they are selling well. I've had them try to alter the price WHILST I was standing at the till. Needless to say I tore the sales assistant a brand shiny new Arsehole. Where exactly are you going in BKK and I'll try to remember if there are branches nearby.
