I'm in, though today was a failure. And after a three day weekend when I spent nothing! Oh well.
I'm a SAHM to two, expecting a third. We had a lot of unexpected expenses pile up in the past few months (including needing to replace DH's car), and have to start making payments on DD's preschool this month. We've been far too lazy about eating out, spending a bit extra here and there for conveniences (paying $22 for the parking garage near where I want to go, as opposed to walking a mile in perfectly nice weather for the $10 lot), and it all adds up. I'd like to have 15 no spend days this month, and 25 days of spending nothing on eating out.
1.

Field trip to a local museum. $8.50 for museum tickets (saved over $20, though, using the library's pass), $27 at gift shop on books, $8.75 for parking. Oh, and 51 cents for the souvenir penny. Also,

$700 on car payment (we pay 2x what we owe to pay it down quicker)
2.

$117 on groceries and $25 on lawn care
3.

(I even returned $37 worth of stuff at Old Navy!)
4.

$40 at JoAnn's, for my DD's birthday dress and July 4th outfits for both kids.
5.

$16.50 on tights and bobby pins for DD's dance recital. Still need to buy makeup and hairspray (don't think I approve of this). And $80 at Amazon on books for the kids.
6.

$50 on gas

$30 on pastries. But well worth it, because they're amazing and we got enough for 2 days. And we had a very active and fun-filled day and didn't spend any other money.
7.

8.

Field trip to the city: $12 for parking,

$10 for lunch for me and fruit for the kids (I packed them most of lunch, but we were out of fruit)
9.

$306 on swimming lessons for the kids this summer. On the plus side, this will help fill up our summer with something pre-paid, so I won't be spending lots of extra then. And it's 8 weeks of 3x a week for DD and 1x a week for DS, so it's a pretty good deal imo. And $60 towards the class gift for DD's teachers.

$20 to celebrate that it's the last day of school.

$80 to the cleaner. And now we're totally out of money until next Tuesday so there are going to have to be some no-spend days!

A ton of money on food ($30 for lunch and $40 for dinner) on food out because it was my

14.

$20 on a babysitter so DH and I could go to my ultrasound
15.

$220 on groceries (eep);

$3 at Jo-Anns, $55 at Dover Books, and $130 at the toy store.
16.

Paid bills! $260 on car payment, $130 on water bill, $548 on excise tax, $80 on milkman, $250 on electricity (2 months worth... oops). Also, $70 on mulch and a trellis for the garden. $50 on gas, too.

$117 at Gymboree, but they were having an amazing sale. I got 25 items including 2 winter coats, and DS is basically all outfitted out for next winter now. $47 at Janie and Jack (will return something), $5 at H&M, $35 on a babysitter. $80 on summer sandals for me: but, seriously, it's been literally YEARS since I bought summery shoes, and these are the first pretty much ever that aren't cheap flip flops. I'm getting too old for that! They're not as comfy as they used to be.

$7 on lunch, $18 on our 2nd dinner because the kids were hungry at the mall.
17.

Another bad day. $95 on Gilt for shorts for DD, a birthday/housewarming present for my sister, a birthday gift for DD's friend, and a baby gift for a friend. So I guess that's not actually a bad deal: I did have a $25 credit, too. Also $100 on sewing supplies from Martha Pullen.

Then all the cash in my wallet at the Farmer's Market, and that had to be close to $60.
