Someone gave me a fancy store gift card, so I am going on a shopping spree and buying stuff that is obviously overpriced that I wouldn't have purchased with my own money.
I returned that unnecessary purchase, and now I am going to use the refund credit for an equally useless product.
Work pays for a society membership, and I will keep renewing annually even though I have no use for it.
I am knowingly overpaying with travel miles in my account for the same ticket as I would have paid with cash.
