I'll relate the sad tale of my couponing for charity first:
I tried to get free dog treats using a sale and double coupons, but our prices must be higher than Couponmom's store, because it would have come to $1 per bag of treats. Not good enough, so I left the coupons for some dog owner to be pleasantly surprised.
Then I went to Walgreens to try the Splenda moneymaker, free maxi pads, bandage moneymaker and super-cheap Colgate. Here's where things went really wrong.

I used a $3 register rewards and 2 coupons, and my total was $8-something. Seemed high but I knew I was getting a $3 rebate and $3 register rewards, so I thought $2 for 2 tubes of toothpaste was an OK deal. (I forgot I'd actually paid $11-something if you counted the register rewards.)

So I was rooting through my bag and realized I didn't get the register rewards. I went back and it turns out if you use a register rewards for the same product, you don't get another one. (That was the maxipads deal.) So I got a $3 refund and returned the maxipads.

After I walked out, I started thinking that I'd ended up spending $5 cash and $3 register rewards, and that I'll get $3 back in rebate. That meant my two tubes of toothpaste cost $5. They were supposedly 2-for-1 AND I had a $1 off coupon, so that means they're ordinarily $6 each? Maybe, but that seemed high. I was going to check the receipt, but then I realized THEY'D TAKEN MY RECEIPT. Not only could I not check to see if I was overcharged for the toothpaste, I also couldn't send in the rebate for the bandages. SO I started out the day with $21.01 and ended it with $12.15. I spent almost $9 for a pack of bandaids and two tubes of toothpaste! Man, couponing is HARD.

It's still going to charity, so it's not that bad. But I was expecting to spend about 80 cents after rebates & coupons, so it's kind of a shocker.

Anyway did much better with the household grocery shopping. We'd had to get more milk and soymilk during the week, so we only had $109 to spend this week if we want to get caught up. I knew we were going to have to buy compostable diapers later this week, which is $16.50, so we only had about $92.50 for our regular weekend grocery trips.

Grand total? $66.40! There were hardly any good coupons, and the website for our grocery store was out-of-date on some of the deals, so I didn't think we'd do that well. But between sales and coupons we saved $19.98.
