UPDATE: Received a check for all four items today.
I sent mine in 11/18. I wrote to the company using their contact form (https://naturesweet.com/contact/) to check the status; here was the reply:
We do show your entry in our system as processing. It was received 12/12/22. Please allow 4-6 weeks as there is a high volume of entries and holidays in between. Please rest assured it is in the system and will be processed soon.
I also wrote back to ask if the 4 products per household will be honored; I’ll update here if/when I hear back.
