Is Xbox Live and Xbox prepaid two different types of GCs?
The terminology may be confusing, but basically Xbox Live gift cards typically come in even dollar amount denominations and are good for purchases, while Xbox Live Gold, Xbox Game Pass, Xbox Game Pass Ultimate and so on are good for subscriptions for X months and are typically priced at a penny under even amount, e.g. $39.99 - though they may be sold at any price. And then of course resellers often show the wrong name - so just look at the description.
