I would be willing to bet that the guy went into the showroom store and put in his custom orders for those two sabers and had them shipped to him. Thats about how long it takes if they don't have a saber there that you want to buy and you get it custom made and shipped. They make a special consideration for local business.
That or its possible he is someone who is "in the know" with Saberforge as a professional reviewer? Perhaps he received these sabers quickly in order to do a review for them? I'm just guessing here, I didn't look at his channel or anything outside of the video itself. This is a longshot though.
One things for sure: he isn't just a random guy who put in an order on the site a week and a half ago and then got them in the mail that fast. Theres just no way. The current *stated* lead time is 6-8 weeks and realistically based on what people have been reporting recently its more like 10+weeks or more. They are busier than they have ever been and theres no way that one random guy got lucky and had sabers delivered from order to door in a week and a half.
Something is definitely missing from the details and I bet its that he lives close and put in his order at the showroom itself. I hate to see you get your hopes up thinking you might have a situation like this happen for you...its going to be a long couple months of disappointment with that mindset!
