2-pack Del Monte Fruit & Chia or Fruit Refreshers @ Dollar Tree w/coupon
If your Dollar Tree doesn’t carry this or there isn’t one near you, Kroger and Walmart (among others) carry this new product as well. There is also a $0.50 ibotta rebate for it (but excludes Dollar Tree), so you’d get $1.50 off with the coupon. I think they’re about $2.20 at Walmart so you’d pay $0.70 OOP. Not free, but a pretty decent deal if you can’t get it for free.
