The Fish Tank Shop makes false promises of free shipping. They will promise you a special gift of free shipping as soon as you add the item to your cart. It says "Buy this product in the next 5 minutes and receive a special gift of free shipping." Then, after you purchase and give them your credit card, they contact you for more money to complete the order. Free shipping is also plastered on their site. Their customer service is horrible and they don't honor their offers. This is illegal and deceptive and they should not be supported. Best to avoid.
