There are some good free competitions that keep appearing here at the moment - it is a UK-only site
Currently including Dobby the house elf Lego (love him so much)
Lego Groot, also love him very much!
Estee Lauder the glow effect set
Estee Lauder Blockbuster set
and JBL 4 speaker
Personally not had any luck on this site yet but they are really nice and gave me a free ticket for a paid comp the other day for reading the newsletter
