The app UI is not good. It is also confusing. There are so many room for improvement. Unlike Shopee if you buy gadgets more than 8k they will give you a voucher 1k off that you deduct and it is always free shipping. The other down side of this app is that there no drop down list for vouchers like Shopee. So if you want to have free shipping fee is to collect and select it manually before you can use it. You can't also change the delivery option of orders.
