Im sorry I dont know every website on the web. I live in NY and NJ, recently vacationed in Miami and Montreal within the last month and I can tell you that NO Diesel store or denim store I went to had these jeans 2 weeks ago. On top of that, no well known online store had them in stock (yoox, neimans, bloomingdales, nordstrom etc). So to me, they were sold out. period.
The point is that you emphasized a false statement that made your sales thread more appealing. The threadcrapping wouldn't have occurred if you didn't "lie". You are liable to your statements as a seller and should be called out if you puposely (or ignorantly) made false assumptions.
