IF that is true, and that is a big IF imho, I would say it is for two reasons:
1. Men feel more guilt over things they have done and think buying flowers, candy, whatever will cover it up; and, 2. Men tend to leave shopping to the last minute and try to make up for it by buying something flashy, while women tend to give a lot of thought in finding something thoughtful, personal, for that connection they feel with the man which frequently doesn't have a big price tag.
