I picked up these gel eyeliners from the Topshop make up range in the sale- it cost £5 for all 3- which is a lot more reasonable than the usual prices which are stupidly high.
In Boots Collection 2000 make up was 2 for £5. I got the supersize fat lash mascara (which so far is disappointing), and an extreme felt tip eyeliner in purple (which is really good!). I also bought the new 17 mascara falsifeye which for a drugstore mascara is quite impressive. It also came with a pot of black gel liner.
