It appears local prices are expensive, and internet normally includes large shipping costs for 1 tank. In fact, shipping is more than the tank. So an ideal situation for a group buy to save on that shipping. Well ... except how many people want 100G water tanks. The tank: 100 Gallon vertical Polyethylene tank made by Norwesco 28 inch diameter. 43 inches high. $163 + shipping from tank depot. http://www.tank-depot.com/productdetails.aspx?part=N-41861 Chosen because it tends to fit in sheds, through doorways, and only weighs 37 pounds. So total cost: The shipping is $188, but the same for 1-4 tanks. Just me = $163 + $188 = $351 per tank. Me + 1 = $163 + $188/2 = $257 per tank. Me + 2 = $163 + $188/3 = $225 per tank. Me + 3 = $163 + $188/4 = $210 per tank. Plus add tax to the above. As comparison, buying locally is $364 for a 100G tank. Limits: Above +3 it gets complicated, so group buy is limited to +3! Mixed orders gets complicated, so group buy is above tank only! (Unless someone else takes over) When: I was planning to place the order in 1 week. March 4'th. Or earlier if we hit the +3 in time. Or later, if nobody is interested. Delivery: The plan is to deliver to my house : Union City, near Dumbarton Bridge/880. In general, you come pick it up. Evenings or weekends. I have a truck, and might be persuaded to deliver locally, for a frag or two, but sorry, not to the city. My guess is a few weeks for delivery, but really unknown.
