Average ticket size on our credit cards fell from $80 last month to $72 this month, and the business is worried customers are trading down. I broke it out: online went from 100,000 transactions at a $50 average to 200,000 at $52, while in-store stayed at 100,000 transactions both months, with the average rising from $110 to $112. How do you explain this?

上个月信用卡笔均消费80美元，这个月掉到72美元，业务方担心客户在消费降级。我拆了一下：线上上月10万笔、笔均50，这月20万笔、笔均52；线下两个月都是10万笔，笔均从110涨到112。你怎么解释？
