Almost without fail whenever someone lowballs me and I say no, then I get the whole price-shaming thing, I end up selling it to someone else within a day or so for full price, or I bump it just to be a dick, and then get that price. I just sold a microwave cart that sat for two weeks. I renamed the title to kitchenette cart, great for dorms and coffee bars, set it $20 higher, and it sold the next day. I bumped a KLR650 after a guy gave me grief, and sold it for $200 more after adjusting the price. So give the price a bump and see what happens.
