FlashFence

FlashFence is a mobile + web app that filters flash sales down to the few that are actually good. Users set “price fences” (target price, max shipping, minimum discount, acceptable sellers) for products or categories, then FlashFence watches major retailers and deal feeds and only pings when the deal beats your fence and is in stock. It also flags common traps: inflated “was” prices, low-rated third‑party sellers, subscription-only pricing, and misleading bundle math. The app focuses on speed: one-tap checkout deep links, backup retailers if the first sells out, and a short “why this is a real deal” breakdown. Monetization is affiliate revenue plus a paid tier for faster alerts, more tracked items, and advanced filters. This is not a generic deal list; it’s a personal deal firewall that reduces noise and regret.
