@picnic My AD states "And with this Auto-Delivery plan, you'll receive future shipments approximately every 12 months for two years". So I assume, next April 2024, and April 2025. Basically it is a total of 2 years but 3 shipments. Nothing about 5 years mentioned.
I did originally try to order on AD but it said sold out. So, I ordered the one time shipment. After completing that order, I saw the little box with the added product on AD. I cancelled my one-time shipment, went back and ordered the AD with the bonus product and had no problems. It was a little odd how it is on their website. BTW, I accessed the TSV through my email so it took me immediately to the product without the bonus item so I was unaware it was available until I placed the original order I ended up cancelling.
