How much should I ask for a used DSLR?

So I'm looking to sell my used DSLR camera and some accessories on either ebay or kijiji and I'm not sure how much to list it at. These are the details:

I've only used these items once or twice, there are no scratches or malfunctioning parts.

Also, I'm looking to sell the camera with all the accessories at once.

Nikon D3200 with AF-S DX Zoom Nikkor ED 18-55mm F3.5-5.6G

Lens (originally bought for $200)

16 GB SD HC Card Class 10 (originally bought for $20)
USB SD/Micro SD Card Reader (originally bought for $10)

Comes with Nikon Battery Charger
Does not come with USB Cable

You can do a search for your gear on eBay and filter the results to only show completed auctions.

You can go to craigslist and see if someone is selling the same gear.

You can go keh.com, which is an online store that sells only used gear. However, keh.com provides a 6-month warranty, and provides exchanges and refunds. They also check out their gear prior to selling it. And lastly, they always under-rate the condition of their stock. I've always gotten gear in better condition than they claimed it was in.

With this in mind, you must sell your gear for about 10-20% less than what the gear goes for on KEH.com.

You can ask $300 for everything.

On average a used camera like yours sells for half what you paid for it new, one with the exact lens you have sold recently on ebay for 305 dollars and another for 292 dollars so you can probably somewhere get around the 300 dollar price range for your gear

Your camera package will easily sell at $100.
