Do not buy from silkies, I had major trouble with them. They sent me things I had not ordered and when I returned them, they sent me bill after bill, eventually threatening me with court action. Every time they sent me a bill I wrote to them enclosing every previous letter and explaining the situation.
in the end I contacted Trading standards who sorted it out with me, and also told me that they had had a very large number of complaints about this company!
Do not let them get hold of your details!
