Piercing the corporate veil

[Belinda R.]

I just formed an LLC and opened a business checking account. When flipping houses I use my Home Depot credit card to make purchases for supplies, appliances etc and pay off once I sell. My question is since this Home Depot cc is in my personal name, could making payments from my business checking possibly pierce the corporate veil. I'm going to try to add my business to the card if I can but with it being a newly established LLC I'm afraid my credit limit will significantly decrease. Thoughts?
