Is there a fee to use Giftly?

Excuse me, I was wondering if there's any kind of fee associated with using Giftly? I'm considering it as an option for a gift, but I want to make sure there aren't any hidden costs that I should be aware of. Could you please clarify if there's a charge for using the service, and if so, what that fee might be? I appreciate your help in understanding the costs involved.
