A QUICK SUMMARY:
Your choice:
--- Participate in Sale offs: YES or NO (globally)
--- Participate in CGTrader Loyalty Discounts: YES or NO
--- The amount of discount: 30-40-50%
--- The amount of Super Discount rate: 30-40-50-60-70%
The amount of discount applied could be different for different assets but
IT IS NOT UP TO YOU. A CGT employee or algorithm makes the decision.
AFAIK CGT has never published the principals their "discount policy" is based on or how the selective use of discount applied on their end works.
My 2 cents:
I think CGT fears that they don't have the coder and technoligical background to handle a much more "sophisticated" discount system in terms of displaying assets and more importantly processing payments. And an "unhandled" system could harm their business and reputation.
A personal note:
I switched on and off discounts randomly for 3 months and I got higher viewing and sales numbers without them. Since then... I don't bother.
But this should be your decision based on your experiences....
