Does that even matter on a AGM battery?
Just playing devils advocate, since I would only buy a car battery locally.
Why would you think an AGM would be an exception? Doesn't matter if it's a flooded or AGM, batteries will only last so long. So a fresher battery is always better than an older battery especially if you lose the receipt at some point and they just go by the date on the battery. I'd like to hear how you think paying the same amount for an 8 month old AGM is just as good as a 1 month old AGM. Like saying it's ok the pay the same price for a 2018 car than a 2019 one.
AGM batteries are less prone to sulfation. Not saying that fresher isn't better, but it is what it is.

AGM has very low internal resistance, is capable to deliver high currents on demand and offers a relatively long service life, even when deep cycled. AGM is maintenance free, provides good electrical reliability and is lighter than the flooded lead acid type. While regular lead acid batteries need a topping charge every six months to prevent the buildup of sulfation, AGM batteries are less prone to sulfation and can sit in storage for longer before a charge becomes necessary. The battery stands up well to low temperatures and has a low self-discharge.
