Should I enter the item value for a free gift?

The item price should be no less than US$1 even for the free item since a commodity should have its own value. Please kindly note that local customs might suspect the item price if it is way too much undervalued even if it’s a free gift. Therefore, we recommend adding full price (or price close to full price) in order to avoid any customs issue (i.e. shipping delay or return issue). Thank you.
