Is it just me, or is it getting more difficult to try to repair something these days, instead of having to replace it

??
I did some maintenance on my pool filter today, and I found a cut o-ring on a bleeder valve on the filter housing.
Now this is a 3/8 th's inch diameter o-ring, not exactly what you would call a low use un-obtainable type part, but after 'visiting' three pool supply stores, I had to go to NAPA auto parts to get a stinking 35 cent o-ring !!!!!!
All of the pool supply stores wanted to sell me a $12 bleeder assembly instead !!!!!
There, I feel better now, that I vented about this !!!!
I'll go take my medication now .
