Have you heard of NanaGram? (https://nanagram.co/). It's a service that regularly mails physical copies of photos to someone you choose, and it's one of the most "of course that should be a product" products that I've seen recently.
One of the big goals of the product is to increase interaction between loved ones. I wrote about this a bit more at https://nanagram.co/blog/niche-start — we have a feature, which allows you to list names and phone numbers of you and your siblings on a cover photo. I get reports all the time of grandparents who go down the list, dialing each grandkid to talk through the photos with them.
I think our prices are pretty solid and often hear that from customers. For $6.99 per month we mail 5 photos and all you have to do is text or email them to us. We also have an annual plan which brings the price down to just under $6 per month.
The service also really shines when you have multiple senders (siblings, cousins, etc) using it as we curate photos from the group via reminders.
We recently had the 5-photo plan set to $7.99 but unlocked savings on the fulfillment side, passing those on to customers.
Pricing has been a challenge for sure, as on one hand I've always firmly believed the product should be accessible to people from all walks of life, and on the other there is a reality of paying the bills.
