Great question! As long as you qualify for the gift you are wanting to switch with and you haven't placed your order yet, then yes! You can visit the Deals page to view the current free gift options. Keep in mind, these are categorized by how much you must spend to qualify!
Curious how to tell which free gift you have selected? “Added” indicates that it is currently in your shopping cart. “Swap” indicates that you can switch your current item out for this one.
