BOWL119 --
First off...your conception of a pro shop business is WAY off. I'm not even going to start on the "two balls an hour" thing, but let's go with that anyways:
He charges $45.00 for both balls. According to you, he just made $90.00. However, if you had the slightest amount of business sense, you would understand that the $90.00 doesn't just waltz into his wallet. He had to pay for the drilling equipment. He had to pay for the drill bits, for them to be sharpened. He had to pay for the spinner, for the polishes, for the abralon pads, for grips, for the glue, for sandpaper, for everything in the damn store. He has a cost of operation, and, more than likely, a rent/mortgage to pay, not to mention other associated costs. That $90.00 is NOT his hourly salary.
Like others said, the $10.00 is ridiculous. Know that your ball is drilled properly, know that it is backed up by a shop, know your pro shop guy, know about the damn ball and the drilling and the surface, and know that you can develop a relationship with your driller. Sheesh! What were you planning on buying with that $10.00?
Is that not worth it? Is the crappy hot dog and small soda at the snack bar more up your alley?
Buying a ball online, at a price terribly similar to that offered at your local shop, is not worth it, under any circumstance, unless you have, for whatever bizarre reason, found an online shop that drills balls the way you like.
Of course, if you can buy a new MoRich ball for $30.00 shipped, that's another story, and I'm sure any pro shop owner with half a brain would understand. Also, staffers who don't drill bringing their new balls in (direct from the company), that's fine as well.
