I was doing some googling a couple weeks ago and came across this site.
They well Lowes discount coupons. There are official lowes coupons. They are emailed to you, you print them off, take them to the store, and 10% off. They work. I've been using them.
I bought a 5 pack of them for 5.50. Saved $250, $100, $75, and $25 with them. So 450 dollars worth of savings for $5.50!
Just passing this along, I know they hand out these coupons all the time, but I never seem to get any.
If you are a veteran you get 10% already, don't know if this will stack with that or not(probably not)
