Lease Finder

Goes looking for money that is already yours but unclaimed: missed refunds, forgotten credits, overcharges and things you are owed and never got round to pursuing.

Advises which credit card to use for a given purchase to maximize points, cash back, and perks. Tracks cards, unused benefits, and misrouted recurring charges.

Landed-cost shopping: real prices, shipping and tax, preferred retailers. Watchlist optional. Never buys unless asked.
