If you're signed up for opi rewards, it'll show you when you earned your points (the days you donated) so you can see when you can come in next. If you're not signed up, you can enroll on the octapharma website.
You can go 2 times within a 7 day period. Those 2 days can not be consecutive. For example you can go Monday and Wednesday but cannot for again until the following Monday
