Does my Walmart Mastercard care where the $ I pay them, comes from?

[AlotanorSki]

I pay my Mastercard off with my AdvCash account.
Let's say I put $5000 on it to pay off my balance. Let's say I do this every month.
Would they ever investigate where the $ came from?
Or don't they care - as long as they get paid?

Barring any extraordinary circumstances (you being on watch lists or involved in/linked to crime), it's unlikely to be of any concern for Walmart.

Your biggest risk would be random spot checks or if they are asked by any authority to investigate repayments from foreign cards.
