Ordering through Lowe's

Here is what happened with my Luba 2XH order from Lowe's. Like Home Depot, the website page for the mower says 90 day return. So I ordered one. But now that the order is in the system it says return by 30 days from the order date. It is taking a week to arrive by FedEx so I will only have 21 days before the return date. I am thinking of starting a return before I receive it and keeping my Luba1. I was going to get an H version of the Luba 2X so I could mow higher.
