CraftSimVendorBuy
Every crafter knows the ritual: you open your profession window, check the queue, realize you are short a handful of reagents, then tab back and forth between the auction house and a vendor hoping you did not miss anything. CraftSimVendorBuy exists to delete that busywork. It is a lightweight companion addon that plugs directly into CraftSim and turns vendor shopping into a single click, so you can get back to actually crafting.
What CraftSimVendorBuy Actually Does
The addon adds a small shopping-bag button right beside the merchant window's close button. That placement is deliberate. It keeps the feature visible without cluttering your vendor UI or rearranging anything you already rely on. Hover over the button and a tooltip shows exactly which missing reagents the current vendor sells. Click it, and those reagents are purchased for you.
Crucially, simply opening a merchant never buys anything. Purchases are submitted only when you click the button, which means you stay in full control of your gold at all times.
How the Missing-Reagent Calculation Works
CraftSimVendorBuy does not guess. It reuses CraftSim's own missing-reagent calculation, including inventory subtraction. That means the addon already knows what is sitting in your bags, your bank, and your reagent storage before it decides what you still need. When you click, it rechecks your CraftSim queue, so the list is always current rather than based on a stale snapshot from when you first opened the window.
The result is a shopping list that matches your actual crafting plans, not a generic "buy everything this vendor stocks" behavior.
What It Buys and What It Skips
Not every item on a vendor is worth your gold, and the addon respects that distinction.
- Buys normal gold-cost reagents that the vendor sells.
- Skips currencies, tokens, and extended-cost items entirely.
- Ignores anything not required by your current CraftSim queue.
- Subtracts what you already own before spending a single coin.
This conservative approach is one of the addon's strongest selling points. You will not accidentally dump honor, badges, or other alternative currencies into a vendor because a button looked convenient.
Requirements and Compatibility
To run CraftSimVendorBuy for World of Warcraft, you need CraftSim installed with its Craft Queue and Shopping modules available. Without those, the addon has no queue to read and no calculation to borrow. Everything else is self-contained and lightweight.
Supported Game Versions
The addon is built for modern World of Warcraft and keeps pace with the client branches most players actually use:
- Retail
- Classic
- The Burning Crusade Classic (TBC)
- Wrath of the Lich King Classic (WotLK)
- Cataclysm Classic
- Mists of Pandaria Classic (MoP)
If you play across multiple branches, check that your addon manager has the correct build flagged for each client, since a Retail install will not load on a Classic realm.
Installing Without the Headache
If you are wondering how to install the addon, the manual route is straightforward: place the extracted folder inside your World of Warcraft Interface/AddOns directory, restart the client, and confirm it appears in the addon list at character select. The folder name matters, so avoid renaming it.
For players who would rather not juggle zip files across six different game branches, the foxygame.net launcher handles CraftSimVendorBuy as a one-click install straight from its addon catalog, which removes the guesswork about which folder goes where. Because the launcher tracks version compatibility per client, it also keeps CraftSimVendorBuy updated automatically, so a patch day never leaves you running a build that silently fails to load.
Troubleshooting Common Snags
Occasionally a purchase will not go through. The usual culprits are a full bag or a vendor rejecting the transaction. When that happens, read the game's error message first, then run /reload before clicking again. Reloading clears the stuck state and lets the addon recalculate your missing reagents from scratch.
It also helps to confirm that your CraftSim queue is not empty. With nothing queued, there is nothing to shop for, and the button will correctly have nothing to buy.
Why It Earns a Slot in Your Addon Folder
CraftSimVendorBuy solves a small, repetitive, genuinely annoying problem with a single button and a hover tooltip. It does not touch your gold unless you tell it to, it skips currencies and extended-cost items, and it leans entirely on CraftSim's accurate missing-reagent math rather than reinventing it. For anyone who queues up crafts in bulk, that is a meaningful quality-of-life upgrade. Download CraftSimVendorBuy, keep CraftSim updated alongside it, and let the shopping bag handle the errands while you handle the crafting.
