I had a couple of cats that drove from Dayton Ohio to NY to sell their dads collection. They emailed me through Craigslist and I gave them my work address (I never have people come to my home). The collection was nice. Nothing too rare or too insane for me to go "ok you're not leaving unless I buy this" but I recall many many Bronze HG books. At least 9.0s with almost a complete set if not complete of Star Wars with multiple 1s. Complete Iron Fist. Many others.
Anyways, the books were packed in 2 suitcases which turned me off cause there were also no bags and boards. I gave them an AweandOffer which they turned down.
Happens to me more than you'd think. I know my budget and know how much I would make out of a collection, and know not to spend a penny over it.
But I wasn't a sour buyer. It was around comiccon time when that happened and I advised them to go and try shop it there. Which is exactly what they did
point of the story, if you're location is not promising for selling comics it's probably not a bad idea to travel to a location where a big con is being held. You'll probably be able to sell a decent collection there for good coin
