My Almost $100 Day today

Today started out innocently enough...DH and I stayed up late watching scary movies on AMC, then woke up today around 1 PM (yes, we like to sleep in late. We are both night owls). DH went and got our lawn mower out, since our grass has grown about 3 inches this week. He tells me we need to get the battery charged, and he needs oil for the mower. We head to Autozone, where they attempt to charge the battery. After an hour, it just isn't happening. Purchase #1: new battery for the lawn mower and oil, $45 total.
Upon leaving Autozone, we head to Dollar General, where I proceed to buy potting soil, bird feed, and insecticide for $10 (purchase number 2). After leaving Dollar General, we head to Lowes, where I wanted to get some cheap flowers for my numerous planters. I am able to find the flowers I need for about $10, which is about what I expected. DH has been wanting a seed spread so he can spread his Weed and Feed he got last week for the yard. The one he wanted was $28. It is one that you can actually push. I found one that was $10, TINY, and hand held, and told him he could get that. He says, Okay! And grabs it. You have to realize, our yard is pretty big. This thing was literally about five inches in size. I had a vision in my head of DH crawling all over our yard for the next week, using this little hand held spreader. I told him to put that silly thing up and get the one he wanted. Lowes/Purchase Number 3-$38. Total for the day was $93.
Strangely enough, I am pretty much okay with every dime spent. Our lawn mower was a gift from my grandma, who passed away in September. I intend for it to last a loooong time. Not knowing a lot about lawnmowers, I didn't even consider it would need new oil and a battery. Apparently, Like cars, lawn mowers have to be maintained. DH can use the seed spreader for years to come, so I am okay with that too.
Our spending for the month is WAY over though. DH thinks we can compensate for it in April and stay within, or even under our $800 goal. I really need to consider everything when setting our monthly budget, so I don't overlook anything, like the multiple birthdays/anniversaries this month.

Gas: $100
