Any Christians struggle with coveting things?

This is one of my biggest weaknesses, and it is taking so much strength right now not to run to the New York and Company semi-annual sale. I know... laugh! But I'm for real lol. Anyone struggle like that? I feel like I don't actually NEED anything, and we are not overflowing with money. We are in debt like everyone else. And yet I still want to run and spend money on myself. Crazy! Anyone else have this struggle and how do you cope with it?
