Is shipping included?

Hi there! Thank you for the opportunity and email. I'm not sure what screen you are looking at but my guess would be shipping is not included. You should have the option to choose standard or expedited shipping which are different costs. I would click on the item and proceed and there should be a breakdown of shipping and the product cost listed. Make sense? Feel free to call me anytime!
