We spend much more on Mother's day than Father's day. In the US, the average amount spent on gifts per dad is expected to be US$135. By contrast, US$186 was spent on Mother's Day presents. 2017 figures: https://www.bbc.com/news/business-40260169
So what are you getting dad for this year? And do you reckon you spent more than on Mother's day? It's interesting we tend to buy more for mum. This year, I spent 70% more on Mother's day, whereas I only took only 20 mins to decide for dad (car care products and chocolates).
