Don't EVER buy carpet from Lowes. Once you are sold carpet they are DONE with you.
If you have an issue you have 30 whole days to have it addressed after that they will refer you to a number that will not answer the phone and basically you are screwed. If you have a stain that you just want to have patched they don't even offer the technical service to provide you with that option. WARNING: DO NOT BUY FROM THEM. THEY ARE NOT CARPET PEOPLE AND THEY DO NOT STAND BEHIND THEIR PRODUCT!
I have done my service to warn you. You can regard or disregard my advice.
