INFO
==========
Details about the codes and how they are formulated.

***Format of current codes - Works for all 10% off $100+, $15 off $50+, $50 off $250+.

• 47000xyyyyRRRRz
  
  10% - 47000yyyyy6036z
  $15 - 47000xyyyy6194z
  $50 - 47000xyyyy6212z
  
  
  • ***RRRR - the 4 digit signature*** - MOST IMPORTANT!!! - Lowe's releases new valid signatures regularly (**i.e. $50 off was 6208 changed to 6209... now 6212**)
    This makes the codes valid, determines expiration.
    • ***Current 4-digit signatures:
      10% off $100+ are 6036, 1534, 6227, 6229, 6035.
      $15 off $50+ are 6194, 6193, 6493, 6228.
      $50 off $250+ are 6212, 6211***
  
  
  • z - check digit - calculated using preceding 14 digits in code - use bulk check digit calculator above
    ***z - lookup EAN-13, turn that to EAN-15 to calculate manually. Excel formula would be something like (MOD(-SUM(MID…*1,*3… google it, then check with me if you want.
  
  
  • x: 0, 1, 2, 3, 4 (***Note: Codes with 5 or higher for 6th digit might be invalid for $15 and $50 off codes. Scroll down for more info on xyyyy)
    x: 0-9 for 10%
  
  
  • yyyy - any combination
  
  
  • ***x is very important in $15 off and $50 off codes:
    In $15 off codes, the 5 middle digits range only from 00001-50000. {470000000164936 to 470005000064934}
    In $50 off codes, the 5 middle digits range only from 00001-55000. {470000000162116 to 470005500062119}
    *The 10% off codes are exempt from this, its 5 middle digits range from 00001-99999. {470000000115341 to 470009999915345}

Previous thread closed. Guarantee to get at least 1 valid & unused code within couple minutes, so PM for code or if need help before you thumb down.

*Lowe's tends to do site maintenance around after midnight, sometimes early morning. Site gets buggy, error messages, empty cart, "Promotion cannot be processed," "Barcode cannot be read…" Avoid making purchases then, wait 30 minutes to retry.*
