I don't normally like to pimp my eBay auctions on here, but the SOTI household is in dire need of its first new computer in nearly 8 years. I'm heading back to eBay for the first time in quite a while to unload a wide variety of books. I've got a dozen or so Silver Age books up there now and will be selling everything from low grade Golden Age funny animals stuff to high grade Bronze in a variety of genres. My seller ID is sma12e.
