Who doesn't love to snack? You can show your appreciation to someone with a great thank you gift basket. Instead of the traditional gift basket, however, say thank you with a large tin filled with various flavors of gourmet popcorn. You can purchase popcorn filled tins online at many Internet shops. Tins are typically filled with either one flavor of popcorn, or they are divided into several sections that each feature a particular gourmet flavor. Whichever type of tin you choose, a thank you gift basket filled with popcorn is a great way to show your gratitude.
