Like all great things Church of God related, there is a catch. It seems the web site where you can order these stickers is also a money making enterprise for a couple of COG members looking to make money off other members. Apparently you can sell anything as 'Feast Gifts" and people will buy it.
The Feast of Tabernacle gift page is here: Gifts
Ties, jewelry, toys, watches, Murano glass and more. It looks like the old money making schemes that several in Pasadena fell for years ago. People bought in with money for the right to sell items from a warehouse catalog that drop shipped items to customers. People were told they would make hundreds of thousands of dollars by selling to their friends and then involving their friends in the scheme. Apparently the tradition continues on.
