Walmart offers the Coleman 27-Piece All Purpose First Aid Tin for $3.70. Opt for free site-to-Store pickup to avoid the $4.97 shipping fee. (Amazon sells it to Prime members for the same price with orders of $25 or more.) That's tied with our March mention and the lowest price we could find now by $3. This crush-resistant tin features a hinge top, embossed first aid cross for easy identification in the dark, and commonly used first aid items.
