Premise: An increasing number of online retailers now allow customers to create "wish lists" of items they would like to receive as gifts.
Explanation: The retailers should explore another method of gift purchases to their customers. One of which can be done through a website to quick analyze the retailer's entire inventory, select a list of items similar to those the customers had purchased and then email the list to a group of contacts specified by the customers which will suggest gifts that are similar to the customer's prior purchase and as such may likely appeal to the customers to have access to various gifts.

Option A - Incorrect
This option does not conform with the argument because we are not sure whether or not the customers use the websites to shop since they only get their delivery from the online retailers after sending them their preference lists of what they want.

Option B - Incorrect
We cannot know this from the argument as we do not know the customers' priority gift-purchasing list. The passage only suggests an alternative approach of gift purchase to the customer which can give them access to a variety of gifts which may likely appeal to them when deciding on the items they want to buy.

Option C - Correct
This is correct; the customers do not use the retail websites primarily to purchase gifts.
According to the passage, they only create a "wish lists" of items they would like to receive from the retailers as gifts.

Option D - Incorrect
This does not have impact on the argument.

Option E - Incorrect
This answer choice is off-topic. We are not sure about the customer's choice as it is not mentioned in the passage if they prefer online shopping to shopping in physical retail stores.
