I think I do the 4 @70 and here's why:
....
I like your reasoning, it sounds great on here, but here is my experience as a business owner for 18 years:
1) Not even close to being accurate - there are value shoppers who will appreciate your other items, there are wealthier guys who watch every penny. There's just no way to accurately guess who will buy the extras and who won't - and I say that as someone who has sat for hours on end, selling his wares at many different venues and experiencing many different results.
2) Can't argue with this, but I can tell you that while you sit there, waiting for the guy willing to pay $70, you are going to experience a tremendous amount of inner turmoil, wondering whether you should be charging $65, or $60, $55, or $50, and so on... until your sheet is full all of the time. You can't put a price on what that does to someone.
3) No arguments there - fewer marks, fewer fixes, period.
4) This is often the most difficult part of being self-employed. Every time you discount something, you worry that your regulars who are paying full freight will find out, and be pissed. It's the same reason I'm also ticked at Sports Illustrated for offering goodies for the new subscriber and nothing for the long time subscriber. This is contrary to all business experience and thinking. If anything, I'd rather throw my regulars an occasional freebie than try to lure in the newbie with first time or odd time discounts. But that doesn't always work either, sometimes you are cutting your own profits for no good reason.
5) Yep, they're not being run ragged - but who really is these days? More likely, every time you look at them during the down time, you will wonder why you even have them around. My business partner falls for this all the time, hoping to get rid of one of the guys who works for us at better-than-starting rates - but who comes through when we really need him, and steps up when we least expect it.
How many people are really giving it their all, ever? 20%? 5%? <1%? As a business owner, you have to hope - and cultivate - the people that will come through in the clutch, and hope they're understanding when you're struggling and can't give them hours when it's slow. It sucks, big time, but it's life as a business owner - every second of every day.
People who are employed in successful industries (read: money makers) will never ever understand what a small business owner goes through. It's analogous to Jones's famous statement, there's golf, and there's tournament golf, they are not at all the same. There's business, and there's competitive business, they are not at all the same. All the theories in the world aren't going to help you when you're trying to decide between making payroll and taking a chance on a new client.
And that's not even close to the rest of the story...
