HexGaming announced a discount on all of their pro controllers, including the recently announced Rival Pro for PlayStation 5, as part of Amazon Prime Days.
The sale, which lasts July 12 and 13, gives 10 percent off any controller purchased from their official site and select controllers via Amazon.
One benefit to this is the ability to maximize via customization. With options costing anywhere from $3 to $30+, it can quickly add up to decent savings beyond the initial cost. Just keep in mind the sale is reflected in your cart, not when customizing, so things will be lower when checking out.
