Alright... so after two attempts I got through to someone on my third try. The first two times had me on hold for 15 minutes before prompting me to leave a message. Third time I got someone around the 11 minute mark.
The part number is V515H47052. No Google hits on that.
FN doesn't have the part. It's on backorder. Price is $4. Nice, right? Well...
I went ahead and placed the order. After taking all my info and whatnot, she asks me how I want it shipped, USP or US Mail. I ask about the cost. Apparently there's a minimum $8 charge to ship, making both methods cost the same.
So I just picked US Mail.
All told, it cost me $12 OTD.
Call me a nut... but I still wish I could have found it third party. The principle alone of paying a 1000% markup on shipping is unsettling.
