I have purchased over 20 machines (about 50% laptop) from dfsdirectsales.com over the last 5 years, and most of them had next day business support still in effect from Dell. I had only one machine that needed service (a Latitude E6510,) and it was repaired at no charge within 2 days.
Also, please use your favorite search engine to look for "dfs coupon codes." I have saved as much as 50% (usually 25 - 30%) using the code at checkout. "Retail me not" has legitimate codes. I copy the code I want to use and paste and apply it when I check out. The discount will show, if the code is valid. A nice customer service rep at DFS Direct Sales told me about the coupons, so it's not a scam. I have been shopping at the US site. Good luck with your purchase, Gilbert
