Aguila 9mm 124 - $100 for 300 rounds ($.33 per round) at Optics Planet.
Says "extended backorder - unknown ETA" on the product page, but after I ordered several more than my wife needs to know about, it says expected to ship February 4 (2021).
I feel like I've become quite a player in the ammo futures market.

One of my buddies has multiple "futures contracts" with Optics Planet. His first order was made in Oct with estimated delivery in Jan (I think, may have been Dec). It's been pushed to April, and that's an estimate. I am guessing that OP has orders placed with manufacturers and have "firm" fulfillment commitments from them. That's the only way I can think of for them to make these offers. Still, it doesn't look like OP is actually getting delivery because the end customer orders are not being delivered. I'm very skeptical that they can deliver at the stated prices.
