I'm glad that you posted about this. Firstly, a legitimate supplier won't lie about the products that they sell or that they have in stock.
Upon checking, the site has been online for less than 2 years. They do have a telephone number that you can call but no physical address. I'm not sure if anyone here has dealt with this supplier before but try to google the website and you will find some reviews/feedbacks from other resellers. One noted that the DVD that he got from them is counterfeit after watching it and judging from the quality of the product.
In conclusion, we do not recommend that you proceed with this supplier.
