What should I say in the first sentence: “”The fee is administered and retained by the vendor, not by this agency “If I accept the fee then I understand that you are still charged through Merchandise.” ” ” Or, if you must keep two sentences (which seem redundant in meaning), use “The fee is administered and retained by the vendor.” The agency does not administer the fee or collect it as revenue. What is the advantage of the second construction of a sentence when the first is active in a normal subject-verb order?
