SellMarked

Mark the junk once and stop selling it by hand.

Alt + left-click any item in your bags to mark it for sale. A small gold price tag appears on its icon. Next time you talk to a vendor, SellMarked sells everything you've marked and tells you how many items went and for how much.

• Every copy, or just this one. By default a mark covers every copy of an item, both what you carry now and anything you loot later. You can switch to marking single items (or stacks) instead, and the mark follows that item around your bags.
• Junk too, if you like. Turn on "Also sell every junk item" and every grey item goes as well, no marking needed. It's off until you turn it on.
• Room for the next loot. Turn on "Throw away the least valuable junk or marked item" and, whenever your bags fill up, the cheapest junk or marked stack (by vendor price for the whole stack) is thrown away on your next click or key press. It's gone for good, so it's off until you turn it on.
• Your click, your way. Pick any combination of Alt, Ctrl and Shift for the mark click.
• Per character. Marks and settings are saved separately for each character, so one character's junk is never sold by another.
• Safe by default. Hold Shift when opening a vendor to skip selling that visit. Items vendors won't buy, like your Hearthstone, can't be marked.
• Sales history. See how much gold SellMarked has earned you, which items are worth the most, what each recent vendor visit sold, and how much junk you've thrown away when your bags were full. Two caveats: earnings don't subtract items you buy back, and only the last 100 vendor visits are kept in detail (the lifetime totals still count everything since you last cleared the history).
• Items you mark while the vendor window is open are sold right away.

Settings are under Options → AddOns → SellMarked. In chat, /sellmarked list shows what's marked, /sellmarked clear unmarks everything, /sellmarked junk on|off switches junk selling, /sellmarked throwaway on|off switches throwing items away when your bags are full, and /sellmarked history shows your sales history.

Tip: a vendor's buyback tab only holds your last 12 items, so mark carefully.
