True Value offers the Pic Mosquito Repellent Coils 10-Pack for $3.99. Choose in-store pickup to avoid the shipping fee, which adds around $7. Outside of the sellers below, that's the lowest price we could find by $3. These coils burn for five to seven hours and repel mosquitos.

Pickup at True Value not an option? Walmart offers it for $5.23 with in-store pickup. Amazon charges about the same with free shipping for Prime members, but with a ship time of 1-2 months.
