Both can be a slippery slope... with coffee many go through different machines, grinders, beans etc., often ending up roasting beans on the back porch each morning prior to grinding and brewing.
Tea can be worse. It's true that really good tea will last all day with re-brews, smoky flavours and subtle changes across the day, but the world of pur-eh (spelling?) tea can take you into the $$$$ literally. It's like red wine, buy it cheap and age it, or if someone else ages it you pay $$$$.
So, how do you take yours? What's your favourite brew?
