Even if you not click stackable discount, they stuck themself without your approval. Very bad customer support, after many request they cannot answer why from retail price 2500 baht i get only 150... What is work , try to contact support and ask to delete all programs, promotion, rates channels etc.. ALL , keep only retail rate. After slowly add your own promotions only and not participate in any campaigns or promotions from Agoda.. If you want to be visible in your city just add Sponsored listing ( 5-12 % extra discount only on booking ) and you will be always in first page of Agoda in your city. I agree that booking or Expedia have fixed discount and never had any problem with them . but many customers in Asia use Agoda so you mast use them as well , unfortunately.
