A price and stock aggregator built for a market the incumbents stopped improving.
We compare listings across dozens of retailers and normalize everything to true cost-per-round — not sticker price, not case-size guesswork.
Who we are
DealsGunsAmmo (DGA) is an independent data provider tracking price and stock across the ammo, firearm, and parts market — giving buyers and the industry an outside, macro-level view of where the market actually stands.
What we’re building
A data-driven platform meant to be the go-to spot for purchasing decisions — comparing offers across vendors and tracking price history, so you can read the market as a whole, not just one listing at a time.
Who we serveNOW
Today, we help buyers on their purchasing journey with price alerts and a real look at where prices have actually been.
LaterNEXT
Down the road, we plan to sell that same market data back to vendors — inventory demand, customer interest and sentiment, and competitive pricing.
