It’s all ears — and chocolate. Just in time for Easter, Costco is selling a 10-pound Giant Chocolate Bunny , and you’ll need a hammer to eat it. The edible bunny is listed on Costco.com at a range of prices depending on local market conditions, with reports as low as $57, while some in-store shoppers have spotted it for up to $140. Made of milk chocolate, white chocolate and dark chocolate, the semi-solid bunny consists of 151 servings, with 150 calories per serving, according to the package.
