I made a similar decision; when I moved, I put a bunch of stuff in storage in my family's garage, including (I hope) my QL books, and forgot all about them. For three years, I never gave them any thought, until my interest in QL was revived when I got the DVDs. After practically tearing my apartment apart, I realized that the books aren't here, that they must be in storage, and I have no idea when I'll be able to get them.
That same attitude made me decide not to buy Song and Dance and Mirror's Edge when they came out and were normally priced. I regret that decision now.
