Especially in regards to furniture, buying online, sight unseen still isn't a great proposition. We don't expect it will ever be.
Perhaps though online could be a great first step filtering process. Find a bunch of stuff that fits the rough parameters of what you are looking for and looks good in your space then go someplace to try them out with a well kept appointment and ready to go same day follow you home delivery should you decide to buy something.
Maybe this already exists? I haven't had to buy any furniture is several years so not sure what the current state of the markets is.
