I know nothing about the company... but Leupold does not allow them to advertise sales that way, ever... and there are a lot of fake Leupold optics floating around out there.
If they are some how gray market or some such thing warranty may be an issue, even though it is in your hand...
Not trying to be a dick, just stating Leupold's well-known business practices do not allow that kind of sale...
They also sell on Amazon. Not my company or anything, but it's actually eBay doing the sale. It's an eBay promo code for spring sports. They listed ~40 sellers that were eligible. It's on their front page. This particular company has a feedback score of 95,181 with a 99.4% positive average.
I also just looked and they are an authorize Leupold dealer on Leupolds website. They have a brick and mortar store front in Coshocton, OH.
