Fantastic Freebies: Crystal Light On The Go Drink Mix and more sample
I'm a big fan of Crystal Light: they're sugar-free and you can them to a bottle of water, making them a much more affordable alternative to Fruit2O and healthier than Vitamin Water.
For a limited time, Wal-Mart is offering free samples of Crystal Light. Just fill out this form and it'll show up in your mailbox.
It looks like ths sample pack also include Kool Aid and Country Time Lemonade, but I'm not sure. Either way, it's free!
