What is convenience worth?
Clearly, everyone has their own breakpoint. But regardless of your income, and even if you are frugal, it's likely you've spent more money at some point in time just for convenience. And to you, it's worth it.
Recently, I've begun using a dog groomer that comes to my home and grooms my dog in RV type vehicle in my driveway. She charges about $15 more than most groomers. To me, it's money well spent. If I didn't work, I wouldn't spend the money. But finding time to take the dog to the groomer, then fighting with her to get out of my car has become a chore that's too draining. To me, the convenience of having the Grooming Wag-In come to my home is worth the additional expense. Apparently, others do too. The woman who runs the business told me she is so booked up, she no longer takes new customers.
In the Opdyke case, I think $2,400 is outrageous for convenience. But I can say I understand why his wife wants to spend it. Where though, do you draw the line?
