One official book button per airline stays below, with a published card or promo only beside that checkout.
Primary button: Open Google Flights (tfs search). Book with the airline there — that is the real ticket (e.g. a US-Bangla ৳ on Google Flights is an authentic airline-issued fare). We do not invent ৳.

Published cards/codes (SCB on GoZayaan, AIRASTRA15: 15% at airline checkout, “SCB card: official up to 10% on this OTA”) sit only beside the matching checkout. If an airline has no published code, show nothing extra. If a real fare is ever known, fare after that percent is labeled estimate from official %.
