SPOTD: Unexpected discounts

I walk up to the pharmacy counter, and suddenly my prescription is half off the price it was last month.  No clue why but who cares!  My Simple Pleasure of the Day is this unexpected discount.

Don'tcha just love it when discounts come to you when:

- You least expect them?  I'm going through a rough money patch, so the extra 40 bucks I expected to use on pills will now be FOOD!  Oh I miss food...

- You most expect them?  It's like going to a store that always has sales by saying to yourself as you walk in "I wonder if they're having a sale?"

- You really really need them?  Like I said... food!
