Prices are the Amazon.com price for a new item. "Usual" is this tool's own price over the past 90 days or the past year, whichever is closer to today's price: the usual range is where it sat for the middle half of that time, and percentages are measured against its median price over 90 days or over the past year, whichever is closer to the current price. Out-of-stock time is left out. ToolBuck has price history for this listing going back 5,675 days. Prices and availability are accurate as of the time shown and can change.
