How should I handle it when someone doesn't like my gifts?

I heard the person I have for secret Santa telling others they didn’t like my gifts. We reveal who we are soon with a final gift. We buy gifts for each day of the week and a final big gift on Friday. We were told to spend around $25 total. I have spent almost double this. The paper telling me about the person so that I could get ideas was about their experiences or items that cannot be found in the country or local stores. I had less than a week to prepare. I don’t know how to handle the reveal. They saw me in the room when they were talking.
