One contest I won the CH purchase a second design I submitted the contest was West Virginian Fair and Festivals...the second purchase was the tent style logo to be used for other promotion events.
The client of one of the contests i won bought one of my designs and asked for a second variation which they got for free. It wasn't a different logo though, just a slightly different variation so its not the same case i suppose
I am thinking that I may eventually have a few logos I like as well. I would prefer to not make an offer directly to the runner up designer as opposed to starting another contest (where only the runner-up(s) will submit) because as the logo buyer I would feel more comfortable with the site's terms and conditions being more binding than just a followup offer. Is this ok?
