Join the Home Depot Orange Insider club and get a $5 off $50 coupon

Still available and still a smart thing to do: enter just your email address and zip code in the banner above and join the Home Depot Orange Insider club to get monthly coupons, discounts etc..  They will send you a $5 off $50 coupon almost immediately.
One of the no-braineriest ways of saving money at any store is simply to join their email list. (I've been on their mailing list for years; just this past Wednesday I got a $10 off $100 coupon on lawn & garden purchases, which we used for getting grass seed, mulch, a new hose and a bunch of other much-needed back yard supplies.)
