Of course! I don't have kids!

Seriously, though, I buy when the seasons change, so here in Texas (since we only have hot and hotter), I really only buy myself new shirts and shoes twice a year. I usually buy DH things then too. We don't go overboard, probably less than $500 a year. I've never bothered to add it up, but I don't shop every month, maybe every other of every third month, for a new shirt here and there. And when I lost enough weight to drop a pants size, I bought two new pair and broke out my old ones. When I have the money to blow on myself, I sometimes find it hard to find things I absolutely love. But when we have children, I'm sure that'll drop a little bit, we will see.
ETA: I guess I should add other things I don't mind spending on myself. I too, will tend to stop at sonic every few days for a fountain drink, they have the best ice. Happy hour is 3-5, so if i go right after work, i can get a large soda for less than a dollar.
I also go to the tanning salon on occasion, so I buy 10 tans for $20, and since I usually don't go all ten times a month, it's cheaper than spending $25 for a month of tans.
I am also about to start getting my nails done again, since we wont' have to spend hundreds of dollars a month on credit card debt anymore.
I don't limit myself to things that I want, within reason. If I want a candy bar, I buy one; if I want a soda, i buy that too. We aren't so tight that we can't afford those tiny luxuries.
