🛒 Roblox Shop System — Game Passes, Developer Products, and in-game currency.

For developers shipping a real economy: purchases granted exactly once, ownership cached, backed by saved player data.

WHAT’S INSIDE
• Never double-grants. Roblox retries ProcessReceipt on network failures, and most shop models hand out the item twice when it does. A PurchaseHistory ledger honours every receipt exactly once.
• Game Passes — one-time unlocks, ownership cached so you are not hitting the API every frame.
• Developer Products — repeat purchases, idempotent receipt handling.
• In-game currency — priced in your economy, spent from the player’s saved profile.
• Cash-multiplier pattern (2x Cash and similar) already wired in.
• One config file. Add products and passes without touching the core scripts.
• A client example script to wire into your own shop UI.
• Typed, commented Luau. No loader, no require-by-ID, no obfuscation — you get the source.

BUILT FOR simulators, tycoons, RNG games, obbies, pet games, and roleplay — anywhere players spend currency.

SETUP is three steps: insert the system, paste your Game Pass ID into Config, press Play.

Roblox’s built-in Shop sells passes, products, and Robux packs in Roblox’s own UI. It does not sell items priced in your currency, run a multiplier, look like your game, or remember what the player owns. This does.

REQUIRES the notamod Profile / DataStore System (included in the Starter Bundle). Full README and Rojo project file included.
