I've been using Comixology for about a good five years now, and have been subscribed to Unlimited for the last two, I think.
It's one of the best deals in comics from my standpoint. The Unlimited library has been invaluable solely off of the volume of shyt they rotate in and out. I've gotten into a bunch of stuff I normally wouldn't have read, or heard about (Thief of Thieves
), or caught up on stuff easily without having to track down TPBs (Manhattan Projects, for example).
You also get an extra 10% off everything, including stuff already on sale.
I really, really wish I could buy more physical copies since that's what I prefer, but the only shops near me are essentially toy stores that happen to sell comics, with the better ones being a decent 20-30 minute drive away, assuming there's no traffic.
And even then, like mentioned in another post, those shops are unwelcoming as fukk. Tons of complaining about "SJW nonsense" because comics aren't just white dudes and half naked how's anymore, flooded shelves of big two comics and TPBs, and maybe just the most popular stuff from Image (which I understand, they gotta stock what makes money), amongst other issues. Most times, even though I miss the feeling of rolling in, spending an hour picking up my shyt I knew I wanted, and maybe some old shyt I've never seen, it's just easier to hit Comixology.
