>>97839952I read all the collected trades via my library system, so if you have that option, you should explore it. My experience is that even in city that won't buy Graphic Novels (which my system in Southern California does - from Image to weird, highly indie self published stuff, to DC and Marvel), most buy certain things like Maus, and a fair amount of Vertigo, which would include Sandman (also because of Gaiman's other published work).
You can find all the issues in digital or scans on a torrent. If you can afford it, I'd at least buy some of the trades.
There are cheaper places than Amazon, In Stock Trades, albeit DC is currently having a sale, so you could buy each trade for $4.99 until the 4th. They usually have a similar sale a few times a year.
