This "I Believe in Mermaids" Handmade Nail Polish drops from $7 to $4.90 through 7/19 at PinkEPromise. Shipping adds $2.50 for the first item, and $0.50 for each additional. Even with shipping, this is the lowest price we could find for comparable handmade polishes by $3. It is only available in the teal color pictured with silver glitter. There is a limit of two polishes per customer. Even better, a portion of the proceeds will be donated to a breast cancer foundation. There is no sales tax (except PA).
