BulkBuy Opens Blizzard’s buy-quantity prompt on every vendor item — including those that normally have no stack-split option — and lets you buy past a single stack.

Why this exists

Blizzard only shows the quantity prompt (StackSplitFrame) on items whose max stack size is greater than 1, and even then it caps the prompt at exactly one stack. This is because a single BuyMerchantItem() call can never purchase more than one stack. For stack-size-1 items (housing decor, mounts, most currency-priced goods, etc.) the prompt is completely hidden.

BulkBuy removes that limitation:

Shift-click any vendor item to open the familiar quantity prompt.
Type any amount up to your configured ceiling (default 100).
The addon automatically queues the required BuyMerchantItem() calls with a short, configurable delay.
No protected or secure code is used.
