I've always wanted to have it, but just can't justify it. On average, I might order one package a month from Amazon. If I were doing 2-day shipping each time, the $7.99/month would just about pay for itself, but I usually just do free shipping, since it's not a big deal to wait 7 days instead of 2. If I would use the other services (movie, TV show and music streaming), it might help, but I wouldn't, so I can't really justify paying it only to get my packages a little earlier. One of these days, I'll likely sign up (though I've been telling myself that for years now).
