However this does make the service that much more visible. I'm not sure that 3D printing is that well known yet. Also, dealing with a B&M establishment provides some with additional assurances that they may not have with an online-only business.

I would argue the exact opposite. Online printing turnaround time is slower, costs more(for printing in batches), and is inconvenient when UPS/Fedex keep leaving "sorry we missed you" notices because you're at work.

As opposed to what? Staples doing the same, but then you have to go pick it up.

In-store pickup is nice in that once it's there, it's there. You can just go grab it at your convenience, instead of dealing with the "can only pickup during this small window" thing UPS does.

Huh? UPS delivers to my door.

Wierd. UPS Delivers to my door only when I am at work. Then, if I don't want to/can't take time off, they tell me I must pick it up between 7 and 9 pm, as those are the only acceptable times, unless I call and arrange a pickup at the office instead of a delivery. If I am really lucky, when I call and arrange for a pickup, they will actually keep it in the office, and won't send it out on the next day's truck. After 3 attempts at this, they return it to sender.

I guess you don't live somewhere interesting and/or don't leave the house.

UPS delivers to my door too - but they literally drop it there, ring the doorbell and leave.

If it's raining, the package gets soaked.

If the neighborhood kids are particularly rowdy, my package is gone when I get home.

Dropping it off at a specific location and requiring me to show up and prove my identity before I can take it home fixes these issues, among others.

BufferBox will solve this problem.
