From the perspective of merchants, there are 6 major marketing tools you can use: Voucher, Discount, Flash Deal, Bundle Deal, Ang Bao and Free Shipping. These marketing tools are reflected on the platform as 6 corresponding functional modules, which originally required purchase to use, now they are all free for merchants to use (in terms of operations, you still need to click the buy button to purchase the corresponding marketing tools, but the payment amount is $0)
