The local Bicycle Co-op, which gets all of their bicycles free as donations, looks up what something is worth on ebay and asks for the same number. Regardless of description, differences, condition, etc. They don't factor in ebay fees, and shipping. The person who usually does the ebay search wouldn't know a Tomasso from a Tomassini.
The result - they have a HUGE area stuffed with bikes and parts they'll never get rid of. They're running out of space.
People are nuts, and I try to avoid these types and focus on the ones who understand the market.
