Normally yes, hazmat kills the deal with online sales. Especially if you are limited to a maximum quantity (e.g. 2k primers or 2 containers of powder).
If you can order a large amount of primers/powder, then it gets washed out with the savings typically. That hasn't happened as of late as nobody has a ton of anything or they have maximum quantities limits in place.
American Reloading includes the price of hazmat and shipping, what you see is what you pay for the item. They have had fairly decent stock of primers lately, hopefully their prices start to drop.
Cheers,
