1. The take-away members of Meituan will open ordinary members at RMB 15 without any discount, and the members who open them will be given six red envelopes for 5 yuan members without threshold, which is equivalent to 51% off when they open them, but if the red envelopes are used up, the extra packages will be purchased at a discount of 21%.

2. If you are hungry, it costs RMB 11 to open a member normally, and you are given four 5 yuan threshold-free coupons. You can buy more red envelopes at a 31% discount (51% discount if you can).

Therefore, in terms of members, it's cheap to add more packages if you are hungry, and you can get a 51% discount at most every day, while Meituan only gets a 51% discount if you buy red envelopes from members.
