I have used Innocam several times to purchase additional camera licences for my synology NAS. The licence comes through instantly and price is pretty much the same everywhere. I pay with PayPal and the price does go up by a couple of pound when you checkout because of the currency conversion rate being different. The emails have “synology” in the subject line which makes them easy to find should you need to reinstall the licences.
Strengths
Easy to use, good service, good price.
