I do typically agonize over any large purchase - and even some smaller purchases such as new video games - for months if not longer. I have continued to avoid buying a new TV, which has proven doubly beneficial - first for not wasting the money, and second because the prices just keep dropping (as expected).
I failed to avoid purchasing a clamshell car-top carrier this past weekend. Been eyeing one for a while - when we do travel with the family to do something such as camping, it's a really tight fit, and only going to get worse as the kids grow up. Some of our friends have bought soft shell carriers and are ok with them, but I really wanted one that would also hold our skis. Those same friends do have significantly larger vehicles that will allow them to put skis on the inside of the car without significantly disrupting the riding experience.
Anyhow, it was a splurge to purchase, but I did manage to get 20% off during Memorial Day, and these things never seem to go on sale - I've been watching. They're also very rarely offered used, and the used ones I saw weren't being offered at much of a discount. Lots of justifications, as you can see, but I do think it'll help a lot for the types of vacations I want our family to have.
