A promotion at Home Depot is offering a Ryobi battery kit for $99, which may also include a free tool. The nature and duration of the sale are unclear, with some reports suggesting it is part of a larger event, such as Ryobi Days or a summer sale, while others imply it may be related to a holiday like Father's Day or Black Friday. The specific tools and products included in the promotion also vary, but appear to include power tools like saws, trimmers, and blowers.
