Not sure how long this will last so if you're interested act quickly. For reference Amazon.com has these for $74 shipped as of this post and retail is $90.
The price is going to be about $40 if you don't have/use Paypal but still a killer deal.
First, go to Home Depot and add these to your cart for $49.97. Add a filler item that's at least $0.04 to get the order over $50 before tax/shipping. In your cart, click the option to add a promo code and use the code PROAPP50 which is a code that says you get $10 off of $50 for buying through the app but as of this post it works just fine from a web browser (Chrome for me) on the standard Home Depot website. Make sure you use all caps and it's exactly as I have typed it.
Now, if you have/use Paypal, go to this link and activate the $5 off of $25 coupon which I think expires today. This one also says you need to install the Paypal app and shop from the app to get the $5 off but if you simply check out on the web browser as described and use Paypal after activating this coupon you should see the $5 in your Paypal account transaction details once the payment posts.
That's it! $90 Peltor 100 electric ear pro for ~$35 or so.
