A weird realization

So... I just realized that I've made several donations lately online. This is not the weird part. The weird part is that I donated by credit card, because I was either donating "at a distance" or for an employee giving campaign. Fine. The weird part is that because I donated with my credit card, I get "rewards points" or some small amount of cashback, or whatever, from my donation. Weird, right? Just another perk of donating I guess, but it is a bit strange.
