One search across every second-hand marketplace at once
Finding a used desk means running the same search on five sites separately, then repeating it every day until something turns up.
Build a search that covers the major resale marketplaces at the same time and returns one merged list, with duplicates collapsed.
Add saved searches with alerts. Most second-hand buying is waiting for the right listing, not browsing.
Filters need to work across sites even though every site categorises things differently. That is the main engineering problem.
Support one city and three or four sites properly rather than everything badly.
