I like to pay about $50. But ReStore prices are high (until they slash to clear things out.)
Breakers add up. If you can use all, they can be worth $5 to $40 apiece.
I've paid $100 delivered, sometimes $200, to get what I want.
I tend to buy on eBay, or Home Depot and Lowes.
Choose first your breaker family. I use Square D QO, not Homeline (which is interchangeable with several brands.)
