FleaHunter: Flea Market Alerts

About this app

FleaHunter searches and monitors four major Japanese flea-market apps at the same time, so you never miss a deal.

"Which marketplace has the best price for this item?"
"I want to be notified the second a new listing appears!"
"I never know the going rate — am I overpaying?"

FleaHunter solves all of those problems.
