This same product was up around 11months ago for $256.45, seems like a pretty handy thing to have for emergencies or if you are someone who goes camping frequently.

Hope this post helps someone out!
These kits are overkill unless it's for a dedicated first aid stand. 90% of the stuff most people won't be able to use properly and could make things worse. Just stick to a small, portable one if you're going camping or such.
