Need help with PSVita sales

I've been trying to sell my Vita and some games, I'll post the list below, but I'm not getting any where.  I posted it locally on Facebook sale sites and I just finished a no buy auction on Ebay.  I priced the whole list according to Ebay prices, and knocked off like $70 but still nothing.  I had it listed for $200.  Can anyone chip in and help with some advice?  Here's the exact ad:

PSVita Bundle

PSVita system Wi-Fi (PCH-1001)
Playstation All-Stars Battle Royale
Touch My Katamari
Unit 13
Little Deviants
Rayman Origins
Hot Shots Golf World Invitational
Uncharted Golden Abyss
8GB memory card
4GB memory card
PS4 OEM ear buds
White Hand Grip

PSVita has a light scratch on the top left corner of the screen.  It's not deep and it doesn not affect game play.  No original box or instructions included, you will only receive what is exactly in the picture.  I will only ship within The Continental United States.  The amount for shipping is an estimate, if the cost to ship it to you is less, I will reimburse it back to your paypal.  You'll know the exact amount once you receive your package.  If it's more, I will cover it.  Thank you for looking.

there doesn't seem to be a lot of demand for the device.. especially with the slim out and most people liking the 3ds more.

personally i've been in the market for a friend, but not willing to go over $100 with hopefully a memory card and/or game... 

most ads around me are asking about $120.

it might be a better idea to sell the games separately, but the problem i see is that most, if not all the games you have, has been offered on PS Plus at some time... a lot of people that own a ps3 or ps4 have already been creating a vita backlog and may see that as an unnecessary cost.

you should have gotten an idea of its current value from trying to sell on ebay or must have gotten offers on local facebook pages, trying going from there.

you can also look into local trades.

As aiman241 has stated, there is not a lot of demand for the device. I see similar bundles for $175 and rarely get bites. Looking at your games, they are quite old and don't get much. 8GB and 4GB isn't really appealing at all as well. Not sure how much you're looking to get, but I don't see getting more than $150-$170 for your bundle unfortunately. The $170 on the absolute high end. $130-140 is more realistic.

I got rid of my 1000 model with Call of Duty and a 4GB for $130, but that's cause I sold it on Amazon and had all the original packaging. So might look at that route and sell it directly to Amazon or on Amazon.

Best bet as aiman241 has stated would be separate listings and as well as looking at local store that is similar to a Gamestop.
