Also, for my emergency/health kits, I got Pepto from Amazon.com. I'm a Prime member, and I have the option of signing up for certain items under their "Subscribe and Save" benefits. I got 4 large bulk-size boxes for $23, roughly 48 sheets of 6 pills each. I got my Advil from Ebay, I found a seller that was selling the 50 packets/2 pills per packet box for about $15 a piece, including shipping.
