Frugal Transgression

So, we had our family portrait done a week ago and we went back yesterday to choose the portraits and, in the end, spent three times as much as I budgeted for. That means we won't go on vacation for a long weekend like we'd planned this summer but I think the portraits will be worth it. The family portrait will be on canvas and looks so professional. I really didn't want to spend that kind of money but our kids are young (and I know that they grow up fast--at least that's what everyone says!) and the photos are, oh, about 100 times better than what we've gotten from Sears and J.C. Penney. So, I pride myself on being frugal but there are times where I think the value of what we're buying is worth the price. I guess this is my frugal transgression for the time being. What have your frugal transgressions been?
