So what is a retailer supposed to do? Sell it for what they paid for it, or just not carry it at all?
They are in business to make money. When wholesale prices go up, retail prices go up.
I think that the jest of what Anarch was saying it that the retailers have been gouging the customers, and not just due to raised manufacturer prices. Oner of the worst retailers in this regards is Cheaperthandirt, who raised their pries 3-4 times they were before COVID, and by-and-large are still quite high in most cases. This is quite clear now that some of the other retailers have actually lowered their prices, and have come down 'close; to pre COVID, but Cheaperthandirt has not.
And doing a quick online search does not always give you the lowest prices. It may give you ammo that is available, but normally the search results will be limited in scope. That is partly why I created my ballistics file - to be able to scan many retailers for any specific caliber, and find the lowest cost, or the most powerful, or if looking for a certain type of bullet. I also created this file to debunk a lot of BS out there about the various calibers, and usually this is about handgun calibers. Many online ammo and gun reviews give out misleading and actually wrong info on ammo, usually because they are biased in some direction - usually pistol ammo vs revolver ammo, although there is a lot about the .45ACP (a pistol ammo) vs. 9mm, or 10mm, or 40mm. And sometimes it is revolver ammo (usually .357 Mag) vs. many of the popular pistol ammo (again - 9mm, 10mm, 40mm).
So, I have built a very extensive ammo file, which covers 35 handgun calibers and 25 rifle ones, where each entry is a link to a website that sells that ammo. In my file I list such things as the box price, the price per round, the bullet type, its availability, and it ballistics, and a bit more. This file has over 3,500 entries (I have been building it for over 10 years), where each entry is a link to an online website that sells that ammo. So, after collecting enough entries per caliber, I can that calculate such things as average price per round, and average ballistics. and also get a range of ballistics, all within each caliber. This means, at a glance, you can tell the minimum power and the max power for any caliber. To make all these calculations, including the ammo's power, the original file is in MS Excel, but I release it in PDF format, so it is safe to all and all can read it. The basic ballistics info comes from the retailer's webpages.
If anyone is interested in getting this file, just message me here, and I will either send the file to you via email, or tell you how to get it online ,if you so prefer. I have already proved the merits of this file here with the person who was looking for low cost .327 Mag ammo, and I showed him a site that sold the same ammo for 20% less. than what he just bought
