I don't know what these people who left bad reviews are smoking, the experience I had with Custom Ink was incredible!
One of my team members thought he was a 3XL but had actually gained a little weight and didn't realize it. They worked with me to get a free replacement one size larger because they said "one of your team members shouldn't need to feel left out".
I also had word art printed on the back and they reached out to me to let me know they were worried some of the smaller fonts wouldn't print well. I didn't have the original file so they offered to have their design team work on it. Turned out amazing!
AND they still shipped it to me in the promised two weeks!
