Indeed. I have been reading a number of independently produced comics, mostly in trade. There is good stuff out there.
The only series I pick up in singles is Rex Libris
, which only comes out every two or three months, so divide $2.99 by three....
I will, however, sometimes pick up a mini-series, or an arc of an on-going title if a character of interest shows up in it, so some months I'll spend as much as $10 on single issues. I buy mostly in trades, and my spending on those varies, as it depends on what titles interest me at any given time. I'd say on average I spend about $20 a month on trades. (For example, I just found a great sale on trades at The Book Cellar, a small chain bookstore, where they were selling older issues of both Ultimate and regular Marvel universes for $6 each. I spent about $55. Other months I won't spend anything. I buy a few titles in trades when they come out, but it's hit or miss. Aaron Williams' PS-238
trade purchases are a given, I bought all of Dan Slott's She-Hulk trades, etc.)
Since I'm guessing you're interested mostly in regular purchases, I won't figure in what I spent the last time I was at a comic book convention....
