I love Step By Step and Growing Pains but hate Full House with a passion. They should include a mail-order offer in all of these DVDs that allows you to purchase the other discs.
The only set I'm getting is Fresh Prince so I'm a little disappointed that the only three shows on the bonus discs I care about (Step By Step, Growing Pains, and WLIIA) I'll miss out on. Here's hoping for eventual seperate releases of them all.
