I buy the plastic Bluewave water bottle jugs off of Amazon, because I have found it a real pain in the neck to locate the 5 gallon water jugs and accessories in any retail locations near my home. If you prefer glass, I recommend these 5 gallon glass bottles.
Rather than drive around from store to store looking, I find it much more convenient and time-saving to simply order it online and have it shipped to my home. The same goes for the reusable replacement bottle caps, storage racks, and any other accessories that I may need.
