1. No matter how many tables, the general rule is 1 person for two packages. Not two bags in a family. You can calculate how many people will attend, then multiply by 2, and add 5- 10% reservation. Colleagues and neighbors who don't attend are also 1 person. You can calculate how much you need.

2. A pack should not be less than four pieces. Buying packaging boxes online is the most cost-effective. It looks good in the box, but it doesn't taste good inside. You can also buy very beautiful ones online. Telford is more in line with the public's taste. Go to the supermarket to buy bulk. You can buy Ferriero if you have better conditions.

3.3-5,000 yuan is definitely enough, unless your family has too many relatives and friends.
