Amazon announced buy two get 1 free sale offer on products ranges from different categories including video games. You can check the list of items on Amazon Promotion Page.
The eligible items must be purchased in a single order and shipped at the same speed to a single address. Discounts are applied proportionally among all eligible items in your order, and you’ll get the most value out of the deal when purchasing three similarly-priced items.
As mentioned, you can also mix and match products. Some categories like movies, music and toys have plenty of items to choose from while others are sparsely populated. The electronics category, for example, has just one item and it probably should be listed in the toys sections. Most of the items in the list are from books and videos only.
