Okay Okay…
This webcomic wallpaper thing seems to have some of you guys thrown for a loop. I’m not sure if this is the exact way to do it (hopefully it helps) Try reading this and see if it works. Hopefully that clears up how the coupon system works and you guys will be able to get some free wallpapers 
If not feel free to email me so we can get this problem worked out.
That one guy,
