Do you buy your olive oil in bulk? (It's not a bad idea; you can save a lot of money doing this.) If so, then consider investing in a stainless steel fusti, a traditional olive oil barrel designed to protect oil from heat, light, and other corrosive influences. This is one of the better deals I've found on these so far.
Includes dripless stainless steel tap, but the stand costs $20 extra.
