I have two five gallon carboys I would like to trade for 6 or 6.5 gallon carboys or better bottles (glass prefered). I know it is not very likely that someone would be willing to trade, but I thought I would throw it out there. I am willing to pay shipping both ways. I would send mine to you with a return label, all you have to do is have it packed, stick the label to it and give it to the driver that drops it off. Or you can drop it off at a fedex location. Or, I would sell them for $30 with free shipping.
