How GameStop store credit will I get if I sell these? Easy 10 points!!!?

I have:
Daxter PSP Great condition
Scribblenauts DS Almost new
Harvest Moon Island of Happiness DS Almost New
Tony hawk GBA Used
Pokemon video GBA Used
Zelda Minish Cap GBA Good
Pokemon Pinball GBA Used
Nick videos GBA Used
Army Men Sarge’s War GC used
Spyro Heros Tail GC Used
Pikmin 1 GC Used
And three other good condition DS games.
How much store credit do you think I’ll get? My Goal is $50 to buy Modern Warfare Reflex Wii!

You’d easily gather up the $50. I think you’d get $100 or more, thinking about it.
