So if i want a 20 gallon non jacketed'its 670. Thats delivered to my door? Or do i have to pay shipping from china to CBB,then pay shipping from CBB to me? Also, this comes with all the fittings becessary? Just trying to understand what makes this so appealing when the 22 gallon brewhemoth, which is made in America, is 639. Also, did anyone confirm through Glacier that their tanks come from this source or did you just take wun hung lo's word for it?
