The biz case here is interesting: I had no idea what the postage rates are from the US, so checked and saw that they start at $1.45. Maybe you can get bulk rates from the USPS but let’s assume that’s the shipping cost. Let’s assume <50c for printing so roughly $2 per postcard. That only leaves $1 for profit & op expenses which sounds a bit low.

Additionally, I would not be OK to enter friends’ addresses in a random app.
