Walmart offers the Fisher-Price Little People Aquarium Visit Set, model no. BGC32, for $9.98. (Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup via Ship-to-Store to dodge the $4.97 shipping fee. That's tied with our mention from two weeks ago and $8 under the lowest price we could find elsewhere. It includes trainer and dolphin figures, a bucket of fish, ball, and hoop.
