All you need to do is log into Roblox in any browser. After logging in, click the Robux icon (resembling a monochromatic stop sign with a white center). It should be at the top right of your screen. You should see your current Robux value there. Just click on it and you'll be taken to the My Transactions page.
Where can I find my Transaction History in the GCash App?
Should be available under the robux tab. Click robux (not buy robux) and you’ll be taken to a page with tabs. Select “my transactions” and you’ll have all purchases and their price dating back since you’ve joined. mine dates back to 2017 and not when I joined. The same thing with my gamepasses tab in my inventory.
