Is this a good price for Lightroom 3?

Nessia

I don't know much about editing my pictures and my current camera I spent way too much $$ on is a piece of crap but I would like to get on the editing bandwagon eventually. I use my MIL's Nikon D7000 thank takes amazing pictures already. I plan on taking some photography classes at ACC. ANYWAYS... should I buy Lightroom 3 for 89.99?
