Have you tried any eliquids from online vendors so far? What price range are you looking at?
My daughter and I enjoy flavors from Mt. Baker Vapor, VaporBomb, The Vapor Room, Killer Juice, Seattle Vapors, ITC Vapes, Vape Wild, and The Broke Smoker. All have a good variety of flavors, reasonable prices and shipping charges, good customer service, and good turnaround time on orders.
None of the above are pre-steeped, with the exception of Mt. Baker Vapor's GWAR line, which are shipped with some steeping on them.
Whether to steep or not depends on how you perceive the taste of the eliquid, with the equipment that you are using. There are some eliquids from the above vendors that we enjoy straight out of the mailbox, and others that we think benefit from steeping for varying lengths of time. My daughter enjoys Mt. Baker Vapor's Hawk Sauce straight out of the mailbox, despite recommendations for steeping for varying lengths of time from other fans. For me, custard and creamy flavors do not start to come into their own until they have steeped for a couple of weeks or more.
It is all up to you. If you like the taste of the eliquid straight out of the mailbox, the vape it. If not, try steeping for a while. Steeping can help eliquids "come into their own", but it is not the be all, end all of vaping. At some point in time, you will encounter eliquids that are not to your taste, whether they are steeped or not. Steeping and price do not guarantee that any eliquid will taste good to you.
