Thank you, everyone, for your thoughts and tips! While it seems that many of you put just about all of your spending onto a card with rewards, that won't be what we will be doing. I am a very visual person, so I took a large wine bottle, washed it out, and decorated it in Disney colors and put it smack dab in the center of our dining room table. Any paper money that can be spared gets rolled up and put into the bottle. The long neck makes it nearly impossible to pilfer the money from the bottle.
Part of my hesitation in getting the basic card (no annual fee ) was that while we budget $200 every other week for groceries and household needs(dog food, soap, etc.), I (1) often do not spend all of that money and(2) shop at Sam's Club for some things which does not accept Visa. So, ideally I'd be spending $7200 on the card in a year, but realistically I wouldn't be. I did apply for and get the basic card to use for gas to start with and will just continue getting the $200 from the bank for groceries. Any money not used at the end of the 2 weeks will just go into the bottle. There was $20 left over this pay period, so into the jar it went. That is 10% of my grocery budget.... more than the1% I would have gotten from the card. I've planned my menu for the next 2 weeks so that I'm primarily using stuff from my pantry and I don't need to buy meat, so I shouldn't spend more than around $100 and will be able to put the remaining money into the jar. Since the1st, we have been able to put about $230 into the jar. Once I can't shove anymore money into the bottle, we will break it open and go from there. Eventually I will use the card at the grocery store and cash at Sam's, and then at the end of each pay period, just take the remaining budgeted money out of the bank and put it into the bottle. I know it probably seems strange, but I'm just super afraid of going over our budget and I don't want to carry a balance on the card.
