Looking for 3-inch ABS no-hub adapters in Seattle area

[ChasB]

I need a couple 3-inch ABS No-hub adapters like this

..but wondering if someone knows of a place in King County that would have them for less than the $14.84 that Ferguson sells them for. I've been to a Lowes, Home Depot and McClendons with no luck. Kind of surprised as I would think needing these for tying ABS into existing cast pipe would be somewhat common.

If it's old cast sizing, 4-1/8" or 3-1/8" sizing, that's a copper size.
I pick up a Mission copper by no-hub coupling for that.

I planned on using one of those but don't I also need an adapter for the ABS pipe to deal with the slightly larger size of the ABS vs the cast iron or will it seal ok and pass inspection with just the no-hub?

Actually I recall that my inspector told me I should use the abs adapter fittings with th no-hub, so I have to get them, just hoping I could find them more reasonably priced

From what decade is your cast iron?

My apologies. I went to Pacific Plumbing and they showed me what you were talking about. My house was built in 1967. The couplings you show are just what I need. I must've misunderstood the inspector. Thanks for your help.
