Yeah I bought 4 #15’s at ACE for $0.59 each. There’s not a Grainger in my area so I’d have to pay postage. I needed 2 and have 2 spares. I did go to an auto parts store and picked up a assortment box but all were to thick in diameter.
I was going to ask Oscar to sell me some, but ACE for me was easy, and I won’t in 10 years from now finding a bag of 98 o-rings in a drawer scratching my head wondering what there for.
Just easier for me. YMMV
