The official cost per ticket is 40 baht. However, these are sold in identical packs of two so it is only possible to buy two tickets at 80 baht (which are an exact match of each other). Also the sellers of the tickets charge a markup. As is the case with almost everything in Thailand, lottery prices are negotiable.
With street vendors, the asking price might be 120-130 baht for the two tickets that have 40+40=80 baht face value. In stands outside major shops, 100 Baht is a common price. Interesting is that vendors who do list prices often do so differently for each ticket. Unpopular numbers cost less while ones containing lucky Buddhist number combinations cost more.
