<human>: Objective: How can you tell if a product you are shopping for at Target is at it's lowest price?

Which of the following solutions is more sound in terms of naive physics reasoning?

OPTIONS:
- Check the price.  If the price ends in an 8, it will likely be marked down again soon.  If it ends in a 4 it will never be marked any lower.
- Check the expiration date.  If the date ends in an 8, it will likely be marked down again soon.  If it ends in a 4 it will never be marked any lower.
