Hey everyone! I'm new to these forums but I was wondering if any of you could help me out! I'm doing a business competition at school and my idea is to produce aquarium kits. I was wondering what wholesale prices look like for equipment and what the markup is! Since my hypothetical company would be buying from wholesalers, I need to know how much they are selling their equipment for so I can get the cost estimate for one kit. Thanks in advance :0
