Hi All : Does anyone know of any great buys for black friday. As a retiree and someone that has had to start afresh with lots of new supplies I want to take advantage of any bargains. I buy Cdn whenever possible and will consider online sales as well. US residents I do like to compare pricing. Canadian residents I have found that "Big Al's Aquarium warehouse" does have a sale on API freshwater master kits. I need to buy new as my present kit bottles are running short because of needing to do fishless cycles on many tanks. Happy goldfish shopping.
