I had a pile going too. I had listed most of the pile on FB but had zero luck. Even when people would respond that they were interested, or wanted more info/made an offer, I would message them and they wouldn't respond. I even would go comment on the post and tag them letting them know I'd messaged them. I could see that most of them had read my message too
I finally listed some stuff on Ebay last week - like I have 2 Victoria's Secret Pink Hoodies that were worn maybe twice... I probably could have done Buy It Now and maybe got a little more, but I put them as auctions starting at $5. They both sold for $14 each plus shipping... So will I get a lot, no, but they're gone and a few bucks is more than goodwill would have gotten me. At least it will pay for the packing tape for the rest of the packages I need to send...
ETA: Now I'm kind of tempted to sell another hoodie I have, I actually wore it more but it's still in very good shape. But on the other hand, it was my very first purchase on my very first credit card, which was a VS store card
