Thanks for this Pete.
Picked up some this morning from Covs.
$17.50 for driver's side & $14.95 for passenger side.
I tried the local Holden dealer for a quote. They don't stock the arms anymore, only the refills and the genuine arms although, strangely, he did have a price in his system. I told him I would pass on the genuine given the price differential. He indicated he might reconsider stocking the AC Delco ones now lol.
Also interesting was one Covs store quoted me the above prices but didn't have them in store so would have to wait until Monday (so next weekend for me) to order them in. The store I got them from initially quoted $20.61 & $17.52 respectively. When I mentioned the other Covs quote they said no worries, I can do that. Only a few $$ I know but I'll take it. I found it strange that the same company has different pricing at two different metro stores.
