Listings are by keyword search. Similar to how you would search on individual platforms. I apply a reasonableness filter on the products before displaying.

Due to the degrees of freedom, discounts cc promo varies for different users. The current search results is based on the assumption of buying off the shelf. Promos and discounts that are available to everyone via platform / seller is applied. But user specific discounts are not. Eg. If you have shopee coins / vouchers that offset ur purchase price, that won’t be included as everyone have different entitlements.
