I love that people are getting into plants. I hate that the trend has driven up prices and made growers do stupid stuff like this to trick buyers.
If you call corporate, it will be almost impossible to actually speak to the person who purchases the plants. Most of the time, you end up speaking to a person with no authority. By speaking to the store manager, who has a great amount of authority, and who knows who needs to have the information, you can get your point across to corporate. If the store manager knows sales are being lost because plants are being tinted and/or have glued flowers, he/she will address the issue.
