I stopped waiting for the exchange rate to hopefully get better, and bought the
Humble Bundle Archie Comics bundle (which expires tomorrow morning incidentally) before I forgot.
They added some really nifty stuff since the original offering, which IMHO, is more than worth it if you read these things at all.
There's some substantial Sabrina and Josie & the Pussycats collections in there now at the pay-more-than-average tier, as well as another volume of the Best of Archie Comics, which comes with contextual notes for stories throughout Archie's publication history (not just Archie, but also other long-forgotten Archie-owned characters like this Donald Duck-copy-looking "Lucky Duck" they used to publish).
And there's also 2 1000-page mega-collections of Archie stories proper, as well.
Very good value for money, and I don't regret spending the $15 for the top tier, even if our petro-dollar has devalued significantly over the past 2 weeks, sigh.
