I used to enjoy shopping on this app, anytime and whenever I wanted with limitless free shipping vouchers but now I enjoy it less because of the limited free shipping vouchers (especially with first come first serve basis) they make us excited in showering us with vouchers but then when the time comes I always end up paying for the shipping at the end (although I placed order on time, it then said "vouchers have fully redeemed") it always makes me frustrated and irritated.
