(A) Parallelism broken on "which pay...and may be shipping"
(B) "That" is incorrect, because this is a non-essential modifier. We're not trying to describe a specific type of small retailer/web site (i.e. the type that pay regular mail rates and ship from one location). We're describing ALL small retailers and websites, then DESCRIBING how they work (i.e. they pay regular mailes rates and ship from one location).
(C) "Who" is for peoples. The "it" at the end is unnecessary. "So affordable" isn't the best comparison marker. One usually says "I am not as rich as you," not "I am not so rich as you."
(D) "Pays" is wrong subject-verb agreement, because our subject is plural (smaller retailers and web sites).
(E) Correct!

Can you tell us the source of this question? It doesn't seem like an official GMAT question, because the comparison structure in all of the answer choices is broken. If we say "[something] is not nearly as affordable..." we need to compare to the thing that it's not as affordable as! A correct answer should say something like "... not nearly as affordable as it is for larger retailers."
