I realize this is a pretty old thread, but wanted to reply how easy it is to add misc shop items for those that may not know how or think it's too hard.
Find free images in off the internet or make your own. Copy them to a folder on your hard drive. (Example: My Documents/Forum Files/Mods/Images)
FTP (upload) them
from your hard drive location
to your
www.BlahBlahForumSite/Sources/shop/item_images folder. To add them, choose that you are adding a "A Test Item". Give it a name, description, price, etc. Select the image from your shop images folder. Make sure the box is unchecked to delete after use.
There are a lot of images already in the shop images folder. Make use of some of those too.
The possibilities are pretty much endless.
I've added some of these items, trying to think of things people would want to buy:
Cocktails: Beer MaiTai Mojito
Entertainment: Dancing Stewie Table Dancer
Gifts: Roses Balloons Kiss
Smoke:Popular for some users
Snacks: 7-Up Greasy Nachos Pizza
Toys:Panda
