My store participated in the 10,000 copy promotion and it looks like, along with the other 15 retailers that took part, we accounted for about 200k copies leaving 450,000 for the other 3000+ stores out there. That's an average of 150 copies per store (a whopping $15 retail).
We constantly hear complaints in this industry regarding the lack of promotional efforts from the big publishers and yet here we have DC committing a large amount of resources toward a producing a low cost, entry level comic book and apparently many retailers chose not to support it.
At a cost of 4.5 to 5 cents each to retailers this book was virtually free. With the backing of AOL/Time-Warner, DC was able to provide this book to us well below their cost so that WE could get as many copies as possible into the hands of new readers. Leave them in coffee shops, doctor's offices and anywhere else you can think of. Give them to every kid you see. Sell multiple copies to your customers and get them to do the same.
