Buying things only when they are on sale!! I try and keep 2 of everything, so we do not run out. 3 weeks ago , my husband used the last of the Miracle Whip so I got out the spare jar, and then put miracle whip on my grocery list. Hey, that stuff is about $3.30 and my dh won't use anything else.
So, I left it on my list, with the note to buy it when it is on sale. (I did the same with olive oil) I found olive oil on sale last week and today miracle whip was down to $1.98.
What didn't I do this before. I got sliced ham (for sandwiches) for $1 off, so today I saved $2.30. I am going to add that $2 to my challenge money.
Prev. total $6405.00
today 2.00
new total $6407.00

Plus, I looked at one of the soft drink vending machines and found a quarter. wow, I never find any money!!
