Who spends the most money on shopping usually depends on the type and quantity of goods purchased and everyone's spending power. So it is difficult to give a clear answer. However, according to the general situation, if a person buys more items, he/she is likely to spend more money.

If many people shop together, they can use the following methods to determine who spends the most money:

1. Record the items and prices purchased by everyone, and calculate the total cost of everyone. This can be achieved by writing everyone's goods and prices on a list and then adding them up one by one.

2. Determine everyone's expenses by sharing the expenses. If everyone agrees, we can split the cost equally. However, if some people buy more expensive goods than others, then this method may be unfair.

In short, to determine who spends the most money needs to be analyzed and calculated according to the actual situation. If there are many people shopping together, you can use the above methods to solve this problem. At the same time, everyone can reasonably control their own consumption and reduce unnecessary expenses to ensure their financial situation is good.
