With orders of $25 or more, Amazon offers the
Coleman Color Changing LED Citronella Outdoor Scented Candle for
$3.88 with
free shipping. That's tied with last week's mention and the lowest price we could find by a buck. It burns up to 25 hours and purports to repel insects.
Note: This item is sold as part of Amazon's "Add-on program" and can only be purchased with an order of $25 or more.
