Magic Tricks

That would be the 'best value' for refills.
3 decks containing 56 card gaffs each for the trick for $39.95.
As the ad states, 168 performances.
FYI - not certain when, but I'm sure that PM will come out with a single refill pack (56 cards) for around $20.00.
They always have in the past.

@JStuff -
You rec'd the same incorrect info that I did also.
The refill decks come w/56 cards ;-)

You may want to check the list of questions already posted and a lot of your answers will be there.
But, since I just logged in -
With the purchase of the original trick, since free flat pack shipping is offered, the quantity of cards is 20ea.
Refills are available. Just do a quick search. Rick's card tricks requiring refills are usually sold as single decks (52cards) or as 3x decks at a discounted price.

I just did a quick search on penguin for contact refill and they have a "3-pack" saver. Are these the only 56 cards refill?
