The reference to CameraLand in NY reminds me also that many online retailers are not actually "authorized dealers" and so, while their prices for some brands are attractive, the manufacturer does not offer their typical warranty if purchased from these sellers.
More complicated still, going through an authorized seller, an "open box" item is sometimes classified under the umbrella term "used"(see adorama) and that can affect the warranty even though the "open box" category is sort of suggested to be new-ish - I believe adorama's "open box" items still come with manufacturer's warranty, though a nikon I bought from them some time ago was also "open box" and they explained a warranty that was different from the Nikon one when I bought it... I wish I could remember the details.
Anyway, we're in a time when online is a common way of buying expensive, delicate equipment. Seller reputation is a just as important as ever, and return policies even more so. I really appreciate the ability to speak to someone who really knows their stuff, and while some big retailers like B&H offer that, they sell so many different things that an "expert" may or may not know about binoculars, or the particular pair in their inventory that you're calling about.
I'm beginning to default to smaller companies with a more explicit focus, despite sometimes a bit higher prices and/or lesser perks, like Optics4Birding.com - smaller company and everyone I've talked to knows more than I do about the product that I'm interested in, and I appreciate the confidence it gives me to make a purchase. They also have a less generous return policy - I think it's 7days and you pay return shipping and restocking fee(!) - and while I don't love that for myself, I think it deters chronic returners from abusing their system and their inventory.
