In reality this post only deals with prices. But one out of three ain't bad. It's 33%, which isn't great either, but it beats ingot droprate.
There's "simple" equasion to calculate what you'll get for any item at any comp. liter skill with any shop:
Price = value x Y x (100+Z)/2733
Terminology:
Price - amount of credits that land in your pocket
Value - value of item as taken from database
Y - shop modifier
Z - Comp. liter modifier
Shop modifiers
Regular shop terminals&NPC --- Y=1
Training area teminal --- Y=1,05
Omni shop terminals --- Y=1,5
Trader shop terminal --- Y=1,75
Comp. liter modifier
This one doesn't change linearly but increases for 1 every full 40 CL skill
Z=CL skill/40, by which you only take full number. Example: Z=135/40=3,375 CL modifier is 3.
Now you have all the info needed to know how much you'll earn in advance. See? Easy.

As seen from matematician view (logic), what's better - ham sandwich or eternal happines?
We all know nothing is better than eternal happines. But ham sandwich beats nothing. So it's no great wonder that most matematicians go around unhappy....but at leats they aren't hungry.
Right.....that's two out of three....66%.....if you're still unhappy at least we know why.
