What is the import of premium contained by "gifts and premium"?
Answers:
It depends on the context but paying a premium is paying above the usual cost of something to get hold of something a touch extra. For example: "You may pay cheque a premium on your apartment rent because you want a covered parking space. A contribution is something you bring for free but nil is expected contained by return. So this phrase appears to bea block adjectives for $ above what is customary or expected.
