I'm sure your intentions are honorable but the topic of pressing service recommendations is in poor taste to discuss here. The topic always ends badly. Please consider dropping the discussion. It's not about violating rules per se but simply being polite to our host.
Pressing services create a direct pipeline for downstream submissions to CGC. In other words, CGC benefits from all pressing services. Discussing them helps CGC, it doesn't harm them.
[Devil's Advocate] Doesn't help CGC/CCS if the prospective submitter uses a different slabbing company and/or different presser. [/Devil's Advocate]
Depends. The more people that submit for slabbing, regardless of the company, the more CGC benefits. At any point slabbing could stop being of interest to collectors and then no slabbing companies benefit.
It's like TGI Friday's and Chili's opening in the same plaza. Both restaurants benefit from the other's overflow traffic.
Or dealers who set up at conventions. They don't get mad at other competing dealers having booths in the same building. They all revel in having a destination place for people to spend their money.
A healthy market, which includes competition, is good for business.
I don't disagree but we're talking about CGC here and they have chosen to do things differently. Whether or not that approach is hurting or helping their business is the real question.
