Hi Sarah, thanks for reading and taking the time to comment. I'm not much of a sparkling water drinker but I do enjoy the carbonation from soda, though I don't drink it much. Sparkling water sounds like a healthier option. I know a lot of people that use their credit card as cash. I think it's good you're using it. The CC companies can see you're using the card, so hopefully they don't close it down like they did mine. Yep, staying under 30%, totally agree.
