This 20oz mug is unreasonably large, and you probably shouldn't buy it unless you want kidney stones. These cost $9.25 to make and $8.99 to ship, so my margin is ~$7. $5 of that goes to pay down my mortgage principal (not usury or taxes) and the rest pays for store expenses, designs, income taxes, etc. Of course, if you buy more than one of the same product type or supplier, I'll (probably) save money on shipping and my net revenue will be that much higher.
If you're poor or would rather not support me or want a different design or whatever, I want to make it easy for you to recreate this yourself. Go to printify.com and find the Jumbo Mug, 20oz by ORCA Coatings (fulfilled by Imagine Your Photos) and use this image:
