Hello Aquel,
I have taken the liberty to search about Sammydress.com. Here are the things that have come up:
They have been online since 2011-05-17, that's about 3 years and their last site update was last month.
They are located in 3/F.,HiChina Mansion,No.27 Gulouwai Avenue,Dongcheng District,Beijing 100120,China.
I also found that they are associated with alibaba-inc.com.
We cannot fully vouch for or against the site since they are not part of our supplier listings.
I hope that our members can provide you their feedback, as well.
Goodluck!
