Is it a sin to covet

:P Usually if I REALLY covet something I would just save up and buy it! Especially LV where it's possible. I mean, I want a BMW M6 but saving up with my salary probably will take forever!
 
^^ That reminds me of the time (in middle school) when my friend and I decided to forgo drinking soda and save up the money to buy a ferrari. I think we did the math and found out it would take us like 300 years...
