Walmart offers the Aqua Culture 1-Gallon Aquarium Tank Starter Kit, model no. ACB002LT, for $7.97. Choose in-store pickup to avoid the $4.98 shipping fee. That's tied with our mention from last week, $2 off list price, and the lowest price we've seen for this model. It includes a full hood with lighting, undergravel filter, air pump and tubing, fish food, and tap water conditioner.
