Munin.VendorBuy
If you have ever stood at a vendor clicking the same stack of thread eight times, you already understand why Munin.VendorBuy exists. This lightweight addon replaces the game's single-stack split prompt with a proper quantity panel, letting you buy exactly as many of an item as you want in one transaction. Type the number, watch the running total update as you go, and confirm. No counting stacks, no repeat clicks, no guessing whether you can afford it.
What Munin.VendorBuy Actually Does
The default World of Warcraft interface lets you split a stack when you shift-click a vendor item, but it caps you at a single stack and hides the prompt entirely on anything that does not stack. Munin.VendorBuy throws that limitation out. Its panel accepts any number you type, shows the cost in gold or whatever currency the item is priced in, and works out beforehand exactly how many you can afford, fit, and the vendor actually has in stock.
Every purchase is validated against three separate limits before it starts, and again before each step of the transaction. If something changes mid-purchase — your bags fill up, your gold runs short, or the vendor sells out — the addon stops cleanly and reports what it actually bought.
Key Features at a Glance
- Type any amount: Ask for 500 and get 500, instead of buying a stack at a time and counting manually.
- Stack button: Fills up to the next whole stack, topping up part-filled stacks already in your bags first. Click again for another full stack, or right-click to step back down.
- Maximum button: Takes as many as you can possibly buy. Hovering it tells you what the limit is — your bags, your money, or the vendor's stock.
- Running total: The cost updates as you type, so you know what you are spending before you commit.
- Smart bag counting: Counts room left in part-filled stacks and will not count a profession bag toward something it refuses to hold.
- Alternate currencies: Valor, marks, crafting reagents, anything a vendor prices in. Each currency is checked separately, and spending more than one lot asks for confirmation first.
- Native look: The panel sits against the merchant window in the game's own colors. With Munin.StyleLib installed, you can switch it to match the rest of your Munin interface instead.
- Configurable click: Use the game's own stack-split click by default, or set it to Shift, Ctrl, or Alt if that one is already spoken for.
Version Support and Compatibility
Munin.VendorBuy is built for Retail and WoW Forever, covering the full spread of supported game versions: Retail, Classic, TBC, WotLK, Cataclysm, and MoP. That breadth matters if you play across multiple clients, because the addon behaves consistently wherever a standard merchant window exists.
It is also deliberately unobtrusive. VendorBuy only touches the merchant window. It does nothing at the auction house and never sells anything — buying only. If you use another addon that replaces the merchant window with its own custom frame, VendorBuy stays out of the way and keeps working on the standard window.
For players who prefer a streamlined setup, the foxygame.net launcher offers one-click installation of Munin.VendorBuy straight from its addon catalog, so the correct build for your client lands in the right folder without manual extraction. The launcher also handles auto-updates, which means your version compatibility stays current even when Blizzard patches a client.
How to Install and Use It
If you prefer a manual setup, download Munin.VendorBuy from your usual addon source, extract the folder into your World of Warcraft Interface/AddOns directory, and restart the client. The process is the same whether you are running Retail or a Classic-era client.
Once installed, using it is straightforward:
- Shift-click a vendor item to open the panel.
- Type a number and press Enter to buy, or Escape to cancel.
- Use Stack to fill to the next whole stack; right-click it to step back down.
- Use Maximum to take as many as you can buy, and hover it to see why the limit is where it is.
Options live in Esc → Options → AddOns → Munin.VendorBuy, where you can set which click opens the panel, whether large purchases ask for confirmation, and whether the addon talks in chat. Slash commands are available too: /vendorbuy opens the settings page, /vendorbuy status shows your current configuration, and /vendorbuy stop cancels a purchase partway through.
A Note Before You Buy
Munin.VendorBuy is provided as is, and no addon can take responsibility for gold or items lost through a misclick. Every purchase is checked against your gold, bag space, and vendor stock before it starts, but it still pays to look before you buy. Treat the Maximum button as a convenience, not a licence to stop paying attention.
Final Thoughts
Munin.VendorBuy solves a small, specific annoyance that every World of Warcraft player runs into eventually: buying in bulk without the tedium. It respects your bags, your wallet, and the vendor's stock, and it stops the moment something changes. If you are tired of clicking the same stack eight times, this is the addon that ends it.
