This week we finally joined Netflix. People have been telling us to join for quite a while, and we finally took the plunge. We joined Monday night (pretty late) and by Wednesday our first movies were arriving. The day after I sent the first one back, a new one was on its way. Pretty amazing.
There is a decent barrage of email from Netflix - no spam, but a lot of status updates and "rate this movie" emails. I set up a filter for them already.
The reason we finally did this was because of the problems with bad DVDs from Blockbuster and their late fees. So now, we can hold onto a kids' video until they are pretty sick of it - no rushing back to Blockbuster by the deadline. And no guilt. Just keep it and return it whenever you want. I like it!
