Sorry for the late reply. I might have already answered this by now somewhere else for you lol but just so you get a reply and everyone else can see how our carts work, I’ll reply here.
BCF uses a persistent cart feature that saves your cart across all your devices for 30 days. So if you sign in on desktop and close your cart then later remember something while you are out and about, and open your cart on your phone, your cart will still be there and you can add items and then go back later, and it should still be there on your desktop with the new items as well.
Carts stay intact for 30 days.
Here is the catch, though. Carts live in your cookies on your device. So if you start a cart today, then clear your cookies and cache tomorrow, your cart will disappear. Those who have regular cleaning of their devices will lose their carts at that time, even if it’s within the 30-day period.
To help mitigate the frustration of cart loss we send an abandoned cart email a day 2 after you leave your cart full so you can see what was left behind 3 months ago (don’t let a cart go that long buy today! lol) If you don’t see this email check your spam folder it might be there or if you have blocked us you wont get it. Don’t be a bummer and block our emails 
We also have a wish list feature that holds up to 99 flavors per wish list. The wish list stays intact until you remove the items. You can make multiple wish lists. Maybe have one for stuff you buy all the time so you don’t have to look around, and have one for things you want to try, etc.
I hope this helps
