For how much can I sell my 2 camera lenses?

I have a nikon d3300 kit lens( 18-55mm with VR ). No scratches or damage.
I also have a sigma 70-300mm DG macro lens which I got for $149. Again, in working condition.
I'm selling as I'm interested in buying Sigma's 18-200mm macro lens. It's around $399. How much can I get for selling the two lenses?

Didn't you learn your lesson from the Sigma 70-300mm? You want an even worse quality lens to go with your 24 MP sensor?

A third to a half what you paid for them even if you do a swap with a camera store.
Get a real macro lens for macro. Stabilise a 70-300 with a tripod.
All in one lenses are only really suitable for travel photos given that they make so many compromises.

You should be able to get at least half price for these used items.

Go to keh.com and see what they sell these lenses for. YOUR price should be less since you do not offer any kind of refund policy, no support, and no warranty.

To see how the Sigma lens performs and how sharp it and other super zooms are (or aren't) go to photozone.de.

With all-in-one lenses, you gain the convenience of having just one lens but at the expense of image quality and often light gathering capability. All-in-one lenses like the 18-200 are specifically designed for those who don't like to change lenses, or need a one-lens setup that is super small for traveling so that they don't get bogged down with gear at the airport. Pro travel photographers will bring multiple lenses with them as it's all about the getting the shot and having a large and heavier kit is something that they're willing to deal with in order to not have to make any sacrifices in image quality or their ability to get the shot.

So just know your needs and understand what you're getting before you do anything.
