Why does a Rocket League bundle show full price if I already own part of it?

If a Rocket League bundle is showing full price even though you already own some of the items, this is expected behavior in certain cases.

Bundles that cost real money

If the bundle costs real money (not Credits), you will not receive a partial discount for items you already own. The full listed price will still display at checkout.

Bundles that cost Credits

If the bundle is sold for Credits and you already own one or more items included in it, the price is automatically reduced. The cost of the items already in your inventory is removed from the total.

Note: The automatic discount only applies when purchasing the bundle for your own account. If you are gifting the bundle to another player, the full price will display.
