I do floppies and trades. Because at times they are cheaper than digital. Hello discount bins.
I also give some of those books away at school.
Some I use for decorations in my office.
I could do digital but in some case I have done it-to help some indy creators like Ray Anthony Height.
I agree with Savior about DC, marvel & Image doing tpb. Why not do a $10 tpb with some months off.
Take a year of Batman and convert it to 2 $10-20 trades for the year. Dc would get $40 if they did 2 $20 (just $8 less using floppies ).
