Kindness, availability, a little inconvenient for the parking issue.
I needed pins for a watch strap, only 4 pins that I keep of spare to replace the strap, 4 pins 8 ...... "they are steel" they told me.
I took them, not mounted but only purchased.
Then once at home, I go to browse online and discover that I can have them at home the next day, Amazon for the same price sells me 360 of various sizes with the tool to mount them, also these in steel.
I don't want to compare this store with online trading, but, 4 pins at 8 = 2 each,
360 pins at 8 = 0.02 each, then 2 against 2 cents.
