People love buying gifts online, and especially if they can ship them straight to the recipient. Therefore, they’ll often want an option where the invoice is left out of the box or pricing is excluded. Perhaps they’re shipping it to themselves but want a gift receipt for the person getting it. You might even want to consider offering special packaging for gift purchases, but only if it’s within your means. Either way, present all of this on your FAQ page so that people know exactly what they’re getting. This is a very common question, and you’ll find that you get a lot more interest from it than you might have initially thought.
