I dont think they are intentionally lying. I've spent over 10k with spec and haven't had any problems to date. I paid in full for both a rooted and sculpted 2 pack set from them and I am still waiting on my shipments as well. These shipping dates are just estimations and it shouldn't be a shock...

I got this one by Ian in case you might be interested
Dunno about Maxnut but the rooted Deluxe did come back in stock recently at Spec, but got waitlisted again. Maybe try signing up for email notifications
