I wanted to purchase something from lowes.com but all the promo codes I was able to find online were coming up as previously used. When I started to analyze the codes that I found online, I could clearly see that there were patterns and just a few of the numbers are different in each class of codes. If you try to change any of the different numbers you will quickly find that you most likely generated an invalid code. This is because
50000?????9218! (10 off 50)
50000?????9346! (15 off 75)
50000?????9382! (20 off 100)
50000?????9388! (40 off 200)
50000?????9394! (60 off 400)
50000?????0151! (10% off)
The ? are random digits 0-9
The ! is a calculated check digit
I’m going to show you how to calculate the check digit.
Currently some of the codes are not working on the current version of the Lowe's Promo Codes app in the Play Store.
I have an updated version ready to roll out but I lost my developer key when I recently wiped my hard drive. Google support wasn't available over over the weekend but I was just informed they updated my new key but I won't be able to update the app until February 7.
In the mean time I have set up a website version of the code generator and it even created barcodes. Just send me an email with some sort of proof of app purchase and I will send you a link to the online Lowe's Promo Codes generator.
