I've been assigned to teach some magic tricks at our summer camp and I was shocked to find a pack of playing cards costing 499 baht in Pata department store. I know vendors are cheaper, does anyone know any cheaper places?

I think I should buy some Uno cards too, as my boss may disapprove of me using playing cards, akin to gambling in some conservative minds. Does anyone know where I could purchase Uno cards in Bangkok?

Thanking anyone in advance.

You can buy playing cards at 7-11

Wifey thinks you can get Uno in the "game" department in Central Department Store. We've introduced this game to our neighbors and her relatives here and they love it.
