Items received!

Even while watching, you are somehow unable to determine how the hovering spinal column hands you the tote bag or drops your purchase into it. When you look inside, you perceive ten compartments of infinite size occupying the same space simultaneously. You were under the impression the human mind either just wouldn't process that sort of thing at all or would go mad from the attempt, but it turns out, it just sort of tickles a little.

Your "bonus gift" was an old, dirty can of aerosol cheese, half empty.

You are momentarily alarmed when you turn to leave and the entire tote bag seems to vanish. The instant you actually want it, however, it re-materializes over your shoulder.
