But not nearly as much as I could have been.
In between actual project work today (which was light), I was researching tires. It was down to two options. A would cost me $308 (including installation, taxes, and fees), is a model recommended by Consumer Reports, and could be installed at a shop less than a mile from my house as soon as tomorrow. B would cost me $285 *on sale* (including installation, taxes, and fees), is a model that seems pretty good judging by general comments on the internet (it wasn't reviewed by CR), and had a much better treadwear rating than A. I went with B, which is through Costco.com, and I have to await their call--within 5 to 10 business days--to see when these suckers can get put on my car.
I also checked out some Honda parts sites and found out that my side view mirror is listed at $179, but at least one site had it for $134. But that's just the part, and I have no idea where I could get it installed and how much labor would cost. I also don't know if I ripped up other things besides the mirror part that I can buy. If I were a little more car-savvy, I'd have half a mind to attempt to install the thing myself, but it involves wires and bodywork and thus is scary.
Anyway, I think $500+ of car work is quite enough for one month.
I should call my mom and make sure she didn't drown now. I'm feeling guilty enough about the car things; I shouldn't have to feel like I have ignored her and the fact that she hasn't been on the internet for a few days and it's OMG raining like fucking biblical floods up there.
