My boyfriend said that my group shopping is actually a manifestation of a poor mentality?

Whether or not to use group buying is a matter of personal habits and preferences. There is no right or wrong.

Compared with the problem itself, I care more about the words "poor mentality" and "no big future".

It feels like someone who is qualified to say this must be a very rich and promising person.

If it is really said by a very promising person, then I respect it regardless of whether I agree with it or not.

But if it comes from someone with no future, I can only laugh.

It is important for people to know themselves. If you don't have much potential yourself, you still need to educate others to be promising. You can't be like a tiger and you can't be like a dog.

Group buying, like all other purchasing behaviors that can obtain price concessions, does not mean poverty in any sense. It just means that you get the same utility at a lower cost, so that you can save money from your limited income. More purchasing power is used for other purposes (of course at the cost of time, after all, there is no free lunch in the world). Anyone can choose group buying. Of course, people who choose group buying instead of group buying are more savvy in addition to saving money. In this sense, group buying itself is a purchasing behavior applicable to any wealth status (although group buying is not available for commodities with high value and utility in most cases).
