Thank you to all who have responded.

I buy my primers in bulk of 5K, cheaper that way. Helps spread out haz mat & shipping fee. Even with that included in price, I can still beat the price of brick & mortar stores around here.

Powder, I try to buy that locally, usually in 8lb when/where I can find it. Fortunately the 45acp is meager on powder consumption.

Buy once fire 45acp for about 10 cent/piece and get free shipping.

Bullets are Hornady 230gr fmj-rn that cost $88/500.
