This price keeps dropping a small amount every day, and could possibly go as low as $ 119 like it was a month ago. Check out the graph for this tool on CamelCamelCamel, and wait as long as you dare for the price to keep going down.
This rotary tool is typically 239 at most major retailers (Amazon/Home Depot). If you apply a 10% off coupon found in this other thread then you can reduce the price to 179.10.

Additionally if you bump your order up to 250 you can use a 50 off 250 coupon to bring the price of the Fortiflex to approximately 160 after the discount.
This is the approach I took and found that the Lowes.com email receipt itemizes each item and applies a discount to each item based on its percentage towards the total.
In my scenario the total was 250.85 before tax and coupon. After the 50 off 250 was applied to the order the Dremel Fortiflex dropped to 159.33 before tax.
