“Bonus treat”??

Hey! I am not a shopper, but my friend just ordered from Whole Foods (via Amazon delivery) this morning and I have a question. In her order, she ended up receiving a “bonus treat” of three items (I believe) that she did not order. The items were accompanied by a little note saying that she got the “bonus treats.” Is this a new promotion? Was she just the lucky recipient of a random act of kindness?

I guess basically I’m asking if I order Whole Foods delivery via Amazon today will I also get a “bonus treat”

UPDATE: yall that’s so weird because I looked at it and it said that it was a Valentine’s Day gift?? It was packaged in plastic and included a note saying it’s a valentines treat and it also had a coupon for hemp, a smoothie recipe, a chocolate bar, and some granola. We are in NC, I don’t know if that makes a difference. I’ve attached photos. The photo of the red note is the backside of the green note in the first photo
