I learned by reading and doing, but I love taking classes, too. With it only being $40 I'd definitely take the class, as someone else said, to get to know the butcher better.
I recently took two French cooking classes locally and they were great. Chef feeds us!! Those were about 3-4 hours and $37.50. Different type classes but great fun.
Go for it!
