Is AUTHOR wrong in the post ? POST : First off some context.

I’m currently in school (Year 10 to be exact or 9th grade in America) and for the last 2 years I have been selling sweets in school. Bringing in a profit of roughly £50 a day average.

Recently a kid who is two years below me began selling stuff as well. Sensing a threat I began selling stuff cheaper for a while so his stuff looked expensive. After around 2 weeks he gave up. Then I went in and bought all of his stock from him for really cheap and sold it on. My friends said this was a dick thing to do, is it?
