I have it, and the first year I felt like it was worth it - closer to $75. They automatically renewed my membership, though, at closer to $100. I'm letting my membership run out in January, and just plan on waiting until I want to order something to sign back up again - I'll see if I can still get that free shipping on orders over $25 OR they try and get me back with a cheaper offer than $100.
Free shipping is easily worth the $100, I just didn't like that they automatically renewed me. I get a lot of our household shopping done there, and supplements, gifts... I use it for more actual shopping than impulse shopping. I don't use the video crap at all, but I do use the music app, but its not my main one. I'm a tune junkie, so when I need that free music fix, it can be an easy option IF they have the song I want on their free list. I don't even bother looking at all the stuff you get for $100, its just confusing and makes me feel mentally weak and consumery.
