A few weeks ago I picked up around 100 or so various Archie comics for $35 through estate sale auction site ebth.com (based locally but they recently expanded nationally). They're not in the best of shape (some water damage, writing on the cover, torn covers in some cases, etc.), but they're still readable. Here's a complete list of what I got. I don't know how many are duplicates of ones I already have, but will go through the list and compare it to what I already have in a little while.
