The account is shared across every demo in the showroom, so items and currency you get in one demo carry over to the others. Loading takes a moment. If the frame is too small, open the demo in a new tab. ## Overview A currency shop lined with coin packs. Press **Buy** on a product under **Buy coins**; the purchase goes through with a test receipt and the coins land in the wallet shown under **Your coins**. The products, prices and amounts are a GS2-Showcase shelf, and each purchase runs GS2-Money2 receipt verification and the deposit as one transaction. ## How to try it 1. Under **Your coins**, note the current **Free balance**, **Paid balance** and **Total balance**. 1. **Buy coins** lists three products: **10 coins**, **50 coins** and **250 coins** (priced 1, 2 and 3 in the demo currency `XXX`). 1. Press **Buy** on any product; the purchase runs with a test store receipt and the page says "Purchased." 1. **Paid balance** and **Total balance** under **Your coins** go up by the coins in the pack you bought. The receipts in this demo come from the platform's test store; no real payment takes place. ## GS2 services used - [GS2-Showcase](/microservices/showcase/): A GS2-Showcase shelf per currency type (JPY / USD / XXX) defines the coin packs with their prices and amounts, and takes the purchase. - [GS2-Money2](/microservices/money2/): On purchase GS2-Money2 verifies the store receipt (the demo namespace accepts test receipts) and deposits the coins into the wallet as paid currency. ## Use it in GS2 Studio In GS2 Studio's Simple mode, open **Add features** and press **Add** on **Currency Shop** to bring this feature into your own project.
