If you like Propel (and boy, does my husband!) here's a super good deal for you:
There is a coupon here for 50 cents off a single bottle of Propel. Typically, I see them on sale at Kroger for $1 a piece (this week they are 5/$6). Using your coupon, which Kroger will double, and if they are on for $1, you can get them for free!
I bought about 15 yesterday for Travis to take in his lunch and with the coupon it was still a good deal at $3.87. I made a pdf of six coupons to a page which you can download here if you are interested. The coupon is good until the end of the year, so I'm just going to plan on stocking up every so often - they make great drinks for Travis' lunch and for taking on outings with the girls for a fun treat. The girls love their "Daddy-juice."
Thanks to Crystal at Money Saving Mom for pointing me to this great deal! : )
