I'm surprised with all the negative reviews on this site.
I've purchased 2 products via this website, both DVD complete series. I've received both of them promptly, and the quality has been impressive (considering I knew they'd be imports). There weren't any commercials on them, the picture quality has been just about crystal clear on all episodes, the audio quality is excellent and one of the 2 sellers even provided the DVD cases with artwork.
The only advice I can think to give about this site is just research all the possible sellers and message them any questions you'd have before purchasing. Also, pay with PayPal. They protect your money and get it back for you if your item never comes (I've had that problem more with eBay than any other site honestly).
