See today’s live deals →The sticker price means nothing without adding shipping. A box listed at $18.99 with $16.95 shipping costs $35.94 — often more per round than a pricier box from a retailer with free shipping.
Cost-per-round (CPR) = (box price + shipping) ÷ round count. It’s the only apples-to-apples comparison metric.
RoundWatch factors shipping into every price comparison. The active retailers and their shipping policies:
| Retailer | Shipping | Free at |
|---|---|---|
| Target Sports | Free | Always free |
| Bulk Ammo | Free | Always free |
| Lucky Gunner | $14.99 | Free over $250 |
| SGAmmo | $16.95 | Free over $300 |
Shipping rates change. Check current deals for verified shipping-inclusive pricing.
Ammo prices are cyclical. They spike around major holidays, election years, and supply shocks — then drift back down. Buying at a historical low vs. a spike can save 20–40%.
RoundWatch generates a BUY, WAIT, or HIGH signal for each caliber by comparing today’s best price to the 30-day average:

Checking prices manually every day is tedious. Price alerts let you set a threshold and get notified when ammo hits that price — so you buy at the bottom instead of chasing the market.
How it works:
Free, no account required. Works for all 7 calibers.
Set Price Alerts See Current DealsBulk buying saves money two ways: lower per-round price and crossing free-shipping thresholds. But bulk only makes sense when the signal is right — buying 1,000 rounds at a HIGH price locks in a bad deal at scale.

Read Weekly Report Get Weekly DigestCost-per-round is the total price (including shipping) divided by the number of rounds in the box or case. It’s the only accurate way to compare ammo prices across different pack sizes and retailers. A “cheap” box with high shipping can cost more per round than a pricier box with free shipping.
When the BUY signal is active on RoundWatch. That means the current price is more than 3% below the 30-day average — historically a good entry point. Prices rise before major holidays and during supply disruptions, so stocking up during quiet periods saves the most.
Typically 10–20% per round compared to buying individual boxes. The savings compound with free shipping thresholds — many retailers offer free shipping on orders over $100–$300, which eliminates a $14–$17 shipping surcharge.
It depends on the caliber and week. RoundWatch tracks Lucky Gunner, SGAmmo, Brownells, Bulk Ammo, and Target Sports USA every 4 hours. The best retailer changes — the deals page shows the current winner for each caliber.
