At $2.99 each and they're up to issue 103 I believe you just stole over $300 from the producers, creators and manufacturers of one of the best comics ever, ensuring that you're less likely to see such quality in the future because there's no profit in it.
Of course that's not really your fault because I'll bet if there were an easy way to download each comic for a more reasonable price, say $0.10 each, you'd happily pay $10 for 100 issues. Otherwise you might be so curious you'd buy issue #1, read it in a few minutes, think, hmm, that was great but it wasn't worth $2.99 at all and never buy another.
