We found this do it yourself box on Happy Money Saver There is a free download for their cute little card to add to a box that you create yourself. Karrie used a variety of her favorite yellow goodies to fill the box. If you are the do it yourself type and want to create a box that is really personal this is a great option.
This little gem is from Parcelly. They put together a clever little box full of fun surprises, including a a Hugs Not Ughs tote bag. This box is $40.93 (they are in Canada).
Last, but of course, not least Confetti Gift Company has several Box of Sunshine options. They have a kids box, a surprise ball Box of Sunshine for all ages and two options that are a bit more adult. Their boxes range from $28-$36 depending on what's inside.
I hope this inspired you to brighten someone's day!
