Nope! There are no extra charges for die-cut stickers.
In order to ensure the best quality for your die-cut sticker, please follow these guidelines:
Make sure that your artwork fits the exact size and shape of the die you have selected.
Be sure that the file includes a 1/8" bleed outside of the entire cut line.
Include a 1/8" safety area within the cut line where there is no text or important images.
If you have a border, it must be at least .25" on all sides.
