The platform will display two prices, one is the market price, which is the merchant's usual offline sales price or the average market price; the other one is the competitive platform price, which is the amount you need to pay.
It should be noted that if the merchant provides promotions such as vouchers, Ang Bao, or others, you can also deduct these discounts before paying; in addition, if you have platform points/coins, you can also use the coins to offset the payable amount.
