Sydney Tools is running a promotion right now where you get up to 20% store credit when you spend at least $250. If you buy this grinder kit for $249, you can get $50 store credit if you also buy another Dewalt product in the same transaction.
This grinder kit has been on sale before but the sweetener is the store credit.
In my case, I purchased this grinder, and a tape measure for 14.95. Total was $262.95, + $50 store credit to use in future.
