Price
I bought it for on holliday (or as we in the states say 'vacation') to England for about £10 in a little shop in Bath.
Personal Review
Fantastic it offers a plethora of card tricks utilizing things like simple math, Magicians Wax, One way back designs, Double Backed cards, The Nikola System (a prearranged deck of which I have never heard) and a few legitimate Psychological tricks.
Grade 8.6/10 I am more into impromptu tricks so I get all sorts of those plus a lot of great ideas just waiting to be expanded upon.
