A word of caution when shopping online, make sure the site you are visiting is a real site and not a fake.
I was purchasing some Thomas Sabo charms online for SWMBO, when I noticed a few odd spelling mistakes so i checked out the site with
http://www.scamadviser.com
only to find that the site I was on was in the Russian Federation, had only been in existence for 3 months and had a very high possibility of being a fake.
It was very convincing, having exactly the same look as the real site.
So be warned!!
