I applied over a year ago to become a Beauty Bible Tester. You can read more about this here. Basically you register your interest and then, if you are successful they will get in touch with you. Imagine my delight when last week I got an email asking if I wanted to be a tester for 2012! All I needed to do was email back an information form and pay £30 by paypal (or cheque) for admin and postage costs.
In a few weeks I should receive a package of products to test and review! x
