Please note that there are limitations in making use of the above offer from Logos Sales:
I have added the coupon code "STUDY20" to one of the logos packages and it did not give the promised discount of 20% as per the promotion.
After chatting with Ben (the manager) at logos sales he first indicated to me that he cannot fix the problem.
Afterwards he stated that because I already own the features section on the package, I do not qualify for the discount. The discount also does not apply to any German packages.
There was no fine print in the promotion, highlighting exceptions to the offer.
It seems that a limited number of users will benefit from this promotion.
