Walmart offers the Coleman 70-Hour Citronella Candle Lantern for $5.86. (With orders of $25 or more, Amazon has it for the same.) Opt for in-store pickup to avoid the $5.99 shipping charge. That's tied with our mention from a week ago and the lowest price we could find by $9. It's designed to repel mosquitoes.
Note: Although Walmart lists this as a 50-hour lantern, the product label lists it as 70+.
