Yes and it should be mentioned, I've sold thousands of dollars of Bitcoins on ebay and you can lose all your money easily. Most the time its people with hacked ebay accounts and you can avoid getting them to buy your stuff by, for example having them verify there paypal phone with you, or there's couple other sure fire methods.
These are easier than Bitcoins to sell but, you should still take precautions, like always having the buyer verify his Cex.io account with you before sending him the code etc. If you take these steps most the time you will scare off hackers.
This being said, I still would recommend selling in small quantities to avoid losing a lot and you may still deal with a hacker from time to time but the payoff is well worth it.
Also, Ebay is slowly (very VERY slowly) but surely taking not and changing its ways with digital currency. Just recently they starting a new selling category specifically for digital currency. I'm guessing  in the future Ebay/Paypal will take note of Bitcoins in its disputes as there's a large amount people wanting this and Ebay is talking about completely implementing Btc in the future.
Anyways, Thanks for mentioning!

Umm.. yeah it may be stupid but people are buying them all day for easily double the price they are on Cex.io. I don't get why someone would either but there's tons of people that I guess don't know how to get Bitcoins elsewhere buying them up. Check the completed listings before you just assume no one would buy these when you really have no idea - http://www.ebay.com/sch/i.html?_sacat=0&_from=R40&_nkw=cex.io+vouchers&LH_Complete=1&rt=nc
Tons of people making a living on selling these vouchers on ebay or sites like fiver etc.

Just made an article on how I can make unlimited cash with Cex.io vouchers. Pretty basic but people new to Cex.io or just looking to make fast cash may be interested - http://freebitcoinsinstantly.blogspot.com/p/bitcoin.html

Most aren't worth your time but there's a few that pay out good and are fun to use - http://freebitcoinsinstantly.blogspot.com/p/bitcoin-faucets.html

Just posted a couple on my blog that are guaranteed to make you as much money as time you put into them. You just need a small bit of Btc to start - http://freebitcoinsinstantly.blogspot.com/p/bitcoin.html
Alternately, if your broke, you can try some some free bots - http://freebitcoinsinstantly.blogspot.com/p/bitcoin-earning-bots.html

999dice has a pretty good one. You get paid every time someone gamble whether they win or lose. Also, the makers put out a bot that gambles for automatically, so if you can get your referrals to use it you will rake in the coins.

Nice, I may check some of these out. I just made my own list of my favorites high paying Btc referral programs on my blog here - http://freebitcoinsinstantly.blogspot.com/p/best-bitcoins-with-referral-programs.html

PB mining is way cheaper plus, there NO fee's whatsoever. Check em out here -

PB mining is currently the cheapest on the web with 1 Gh/s currently at 0.0056 Btc.
They are better than Cex.io because there's no fee's whatsoever once you have your Gh/s, there cheaper to buy and 100% insured for any bugs or downtime. They also offer a generous 10% of all your referral earnings so you can make alot of money here if your good at getting referrals.
They pay out every week to the Btc address of your choice and they are currently mining Bitcoin with a total hash rate of 235 TH/s.
The only downfall is your GH/s only lasts 5 years and as far as I can tell you can't trade your GH's, however with all the benefit's I still think there by far the best.
Check em out if your interested.
