I guess my point is.....at what point isn't it worth it? These sites have gone from 90% success rates to the already 50% or lower at best success rates they've been seeing on the last couple of releases. (Chalk it up to oversaturation of these sites, Niketown location shadiness, etc.)
There exists no doubt in my mind they will try to tweak or even develop new programs to counter whatever Nike's doing. But all of that takes time and money. At what point do you determine the money because of low success rates isn't worth continuing developing for?
