Not only is this variety pack cheaper than buying individually, but is also guarantees you will get 5 different figures. As a collector for a long time now, it can get very frustrating buying 5 packs at £2.00 each to find that 3 are the same, and this puts an end to this problem, making them, for me, nicer to collect. The display stands are brilliant too, are compatible with Lego and even stack up to display well. The designs, although some are the same as before, are all really nice too. On top of this, when you take the base off to open it, you'll find the parts to the figure are all in a nice little plastic bag, meaning that you can open them wherever and not have to worry about losing pieces. Very impressed.
To give an idea on how figures vary, I got The 9th Doctor, The 10th Doctor (Long Coat), The 11th Doctor (Fez), Gold Dalek and Dalek Sec in my variety pack.
