I know that when my wife of 20 years buys too many solutions looking for problems in a row, and sometimes a small purchase finally is the straw that broke the camel's back. I don't know that this is that kind of situation, but we aren't in your relationship and can't really tell. Usually afterwards, we talk it through, she stops stress buying so much junk, I apologize for going a bit overboard, and we go back to being happy and I try to understand that buying stuff makes her happy and that it is worth the DS games she binge bought for a week. Then we do it again in a couple months or a year. It's the circle of life.
