You get flare every month, or you get to read each month's issue depending on the type of membership you opt for.
I see alot of "what do i get out of it" and "value for my money" concerns. First off, the subscription to Flare is cheaper than any other mag you will ever subscribe to. There is also the IBC store, not always the absolute cheapest you can find the stuff for, but fantastic deals none the less. There is also the large community of betta fans and breeders, the best in the country, and most of them don't post here.
Now i know this place is a great place for betta knowledge, and there are people with experience here, and i'm not trying to put anyone down, But this place is like elementary school, and the IBC is High School and College by comparison. There are lots of people there who have bred hundreds of thousands of fish, tried every additive, food, housing that exist. And they also develop some of the techniques that will become the new standards in the years to come.
There's also the intangibles. The IBC is the organization that really pushes the Betta hobby. If you look at the chain stores these days you can find exotic morphs like DT, CT, Dragons, Giants... just a couple of years ago your choice was veiltail, or veiltail. Your money to the IBC is in part used to make that push, to spread the awareness, and bring more people to our hobby. That interest in our hobby makes suppliers create more products for us. It also makes those products and fish and everything else more accessible.
One more thing to note is that for most of us that breed in this country, most of the fish we breed and sell are for breeding, for the show circuit. The IBC is the show circuit.
So basically there is some stuff you get. but mostly you're ensuring the hobby and it's growth, which has it's own rewards down the road.
