Anything premade is on a first come first serve basis. Noone will have the same logo as someone else. Similar design style or elements may be used in another logo but it will not be exactly the same.
Be sure to include name of premade choice if you are wanting to purchase anything that is premade.
If you are wanting something custom made please be sure to include what it is you are wanting and I will email you back as soon as I get a chance.
