Total cash for the following at gamestop?

I know what the majority of people want to say "sell it on Craigslist or ebay" problem is it takes to long and I need to have 550$ total by the weekend, I've spent 3 months trying to sell my Xbox one day one edition + 2 games on Craigslist and only a minute ago I got it sold for 385$ Now I 180$ at least for the following

Xbox 360 slim 4gb with everything except box

2 xbox 360 wireless controllers

Black ops 2 (360)

2 copies of World at War (360)

Modern warfare 2 and 3 (360)

Skyrim legendary edition (360)

16 gameboy games (I'm sure it won't help a ton since these sell for cheap)

2 game boy advance sp

IPhone 4 8gb Verizon black

Here is what I think you will get.

$30 - Xbox 360 slim 4gb with everything except box

$10 each - 2 xbox 360 wireless controllers

$5 - Black ops 2 (360)

$3 each - 2 copies of World at War (360)

$3 each - Modern warfare 2 and 3 (360)

$6 - Skyrim legendary edition (360)

$1 each - 16 gameboy games (I'm sure it won't help a ton since these sell for cheap)

$15 each - 2 game boy advance sp

I don't think gamestop will buy this - IPhone 4 8gb Verizon black

TOTAL: about $120
Just a guess. Even if I'm not completely right with the prices, it won't be a $60 difference. I'd say give or take $20

Consider selling at a Tag/Garage Sale. 50% to 75% of retail., Ask for as much as you want. If the buyer isn't interested, you can haggle or either of you can walk away.
Pawn shops 5%-10% of retail. Or less.
