Assuming for a moment that there's no fraud with this company, this is a great example of how you can quickly go broke selling a popular product. If the payment terms, product delivery logistics pipeline, etc. are more protracted than your suppliers', you will get strangled by your accounts payable before your receivables can save you. This was the genius of Dell's built-to-order system: they had (have?) a negative working capital position.<p>Of course it's also a great example of how you can, if you're not careful, light a pile of money on fire with performance ads. Please, people, please, test your advertising!
