I visited Sardinia this summer and when buying the first batch of postcards, I asked the cashier in the souvenir shop for stamps. He sold me a couple, but when I was sticking them on later, I found that the stamps looked different from what I previously bought elsewhere. I looked online to find some information about them and found that people complain about this service as being extremely unreliable and slow.
When life gives you a GPS stamp, make an experiment, I thought. So I obtained stamps from all three available vendors and sent myself some vacation postcards from Sardinia to Czech Republic. Here are the results together with some notes about each vendor:
Poste Italiane
Globe Postal Service (GPS)
Friendpost
From my experience, none of the services are as unreliable as the people on TripAdvisor say. Friendpost is the slowest, but I think this is because they have a sparse network, so they cannot afford to collect the postcards as often as GPS.
In none of the cases the delivery took several months, although it is slow indeed, especially considering that they were delivered within the EU. I recently received a postcard from New Caledonia, about 6 months after it was sent, so things could be worse than that.
All of the postcards arrived to their destination okay, none were lost or damaged.

I have not experience about the timing, but consider that in italy the postal service is Poste Italiane, 99% of italians use Poste Italiane for normal mailing services. You can find an office in every village (their logo), in the small villages is usually open only in the morning (like 9:00-13:00), in cityes all day. There you can buy the stamps and send the postcards (but don't expect they speak english though...).
The two services Poste Italiane offers for international mailing are the normal one and the fast one, timing and costs depend on the destination, unfortunately i didn't find an english version, sorry.
