Drain Cleaning Coupons for you...


All coupon offers are not equal...

and because we value honesty and integrity we want to make you aware of the fact that there are other companies that offer a higher discount coupon... BUT they do so because they charge a lot more for their services. Which means that a $20, or $30, dollar savings coupon is not a bargain when you have to pay two or three times more for the same service you can get from us.

We already offer EVERDAY LOW PRICES at Dennis Diffley& Sons and you could save more with us without any coupon then you will from a company that lures you in with a big coupon offer, but charges you an arm and a leg for their services. Remember: All that glitters is not gold...So before you make a decision to use a coupon because you think it saves you more, make sure it is a real value and not just a tactic to bait you into paying a much higher price for the same service you can get from our Everyday Low Prices.

One quick call is all you need and your problems are over. So to get you started today here are some real value coupons* we offer to save you a little more money off our already Everday LOW Prices.


Check out our Discounts for Senior Citizens, Active Military Personnel, and First Time Customers.

We will not be under priced on any valid estimate of service from a legitimate competitor's prices! Give us a call for a price comparison before you sign on the dotted line.
