I had not read every guess regarding what Ashley had purchased, as there have simply been too many for me to keep track of. At least one person on Twitter, however, not too confidently said that their best bet was a soccer ball, and it took all of my will power to not respond in some way.
In any case, anyone who guessed soccer ball? High five. Bonus high five if part of the reason you guessed that was how Ashley was evidently holding whatever she had acquired in the previous comic (both hands holding the box with the ball in it).
