A blister pack and package including such blister pack is described which provides for package stability and self-indexing in relation to adjacently aligned packages. The blister pack is configured to include at least one compartment for enclosing an article, and an outward projecting portion or foot in the bottom portion of the blister pack. The foot is configured to have a width, depth and height sufficient to allow the package to be freestanding and self-indexing. The package is especially suited for use in a merchandise point-of-sale display including a pressure applicator for maintaining displayed packages in a forwardmost position in the display when one or more packages are removed from the display. The foot provides for a predetermined stable spacing during packaging and while in storage and on display, and provides for self-indexing, i.e. maintenance of proper spacing, when a pressure applicator moves the aligned packages forward in a display.
