How do gift certificates work?

I know this may be a stupid question, but how do the gift certificates work, as in what happens when someone purchases one? Do they receive something in an email, or do we need to find a company that creates plastic gift cards, etc.?

Not sure about your version but the latest version adds it to the baskets and they can print at there end or just copy and paste the number when purchasing further items.

you can also add them manually in the gift cert area and have a virtual one emaile dto them.

Remember to activate the discount code if you create them manually.

When the customer enters the number at checkout the amount autoatically gets deducted.

It works great for me , we use it all the time.

Sorry it took so long to get back - thank you for your response!
