Estimation 8-(

I finally went grocery shopping again and this time I was a little more conscience of what I was spending. I didn't throw everything into the cart that I wanted and did some estimating along the way so I knew where I was at. There only problem was that my estimations came to $134.00 for the bill but the actual bill came to $140.02 That isn't good if you are trying to stick to a budget so I guess the next time I will have to bring the calculator with me. Otherwise I haven't been spending like I usually do and spending way more time at the house because it prevents me from spending unwisely. So here to the weekend, I have $60.00 until next Wednesday. Hmmmmm, will it last?
