Amazon offers Prime members the Kyjen Hide-A-Squirrel Puzzle Toy for Dogs, model no. PP01056, for $7.79 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $6.52.) That's tied with last month's mention and the lowest total in-stock price we could find by $5. It features three squeaker squirrels hidden inside a plush tree trunk.
