I've ordered tons of photography and video related stuff from primarily these three places over the years. With so many incidents of porch theft happening nowadays, it's of tremendous peace of mind that I now have the option to redirect my packages to a convenient and secure local store where I can pick up the package.
Of the three, my first go-to place for spending my money is Amazon because it offers the most flexible ship redirecting experience. For one, I can even designate a local place other than my home address as a place to pick up my packages before placing the order. Even after the package has been shipped to my address, I can simply log into my UPS account and redirect the shipping to a local UPS store that's only a half mile away. The same if shipped via FedEx. If USPS, the package gets delivered to my community mailbox with a key.
With BH Photo, redirecting my packages isn't as good as Amazon, but I can redirect the UPS shipping to the central UPS location which is about 10 miles away. Not very convenient, but at least it's better than $2-3K package sitting in front of my front door for hours. I've discussed this issue with them, and basically their response is "this is the way things are done here, so just accept that fact and move on."
With Adorama, from whom I just placed an order for a Canon L lens, I just learned from online chatting with a staff that they can only redirect the packages by my contacting them EACH time I place an order because of their "contract" with the UPS (and I assume with other delivery companies, likewise).
Neither BH Photo nor Adorama seems willing to "listen" to what concerns many consumers, i.e., more secure way to receive very expensive photography or video products in today's high incidents of porch theft. Apparently, neither is interested in studying and emulating the extremely successful and profitable business model that placed Amazon as the most successful online merchant with Bezos as the richest billionaire in the world.
I will continue to shop at BH Photo and Adorama but only when the pricing or certain promotionals are significantly better than at Amazon -- which isn't all that often. Hope BH Photo and Adorama are more willing to listen and better gauge the needs of consumers out there.
