I think the majority will tell you to not buy into these types of clubs. But, keep in mind that the feedback of "no" comes from a group here who have been smoking for years and have developed a pallet and know which flavor profiles/countries they like. So there is absolutely no need for them to join a club.
I don't know how long you have been smoking cigars but if you are newer to the hobby, then it might not be a bad idea to try out a Monthly Club so you can taste random sticks and learn what you like and don't like. Doing this, and listening to the experience of the BOTLs here, will develop you much quicker.
I kind of look at it like this (and this does not include all the trades/passes here on BOTL): First year of really getting into smoking, try a monthly club. Then start transitioning into buying 5'ers of things you like (flavor profiles, country of origin, sizes, etc). If you love cigars and are into the hobby at this point, start looking at bigger purchases so you can start aging sticks.
So, I think
@VeLoRoK makes a solid point and as usual, this is just my 2 cents.
