As you now know, always check with the Live lecture series before buying an older release type of trick.
Yes, a lot of times, the trick is shown in the lecture as part of the total presentation.
This, coupled with the additional info from the lecture, will usually make the Live series a better value.
'Money' by Jay Noblezada (not really a Live presentation, but...)is another that comes to mind that includes numerous tricks that are singled out for sale separately e.g. '5 in 1 Transpo', '2 Dollar Window', 'Cornered',
'Torn and Restored Bill', yada yada yada, as instant downloads ranging in price from $9.95 to $14.95.
Since the Money presentation only costs $29.95, the added value is obvious. Money has at least 16 different tricks/puzzles that are fun/easy to learn/perform.
Best wishes...
