Asylum Packs question

By Azathoth the Elder, in Call of Cthulhu LCG

Hi -

New to the game and enjoying it quite a bit, but having some difficulty with buying the Asylum Packs. My LGS has quite a few of them, but some contain 40 cards, some 60. Is the difference in the card titles that are included, or more copies of the same card? And if I buy the 40-card packs, will I be buying the same cards that I would get in the (presumably newer) 60-card packs?

At first, the cards were released in 40 card packs, a total of 20 different cards, where some cards had 3 copies and others only 1 copy.

Then, they changed the format to 60 cards, where there are 3 of each of the 20 different cards.

So nothing changed in terms of the cards, just the numbers. Clearly it is better to buy the 60 card packs because then you have a play set of everything. I used to buy 3 packs of the 40 card sets ($30), now I just buy 1 of the 60 card set ($15). Half price!

A belated thank you for the information - appreciated!
