Useless Shops

[scubab]

I was thinking about throwing together a guide with screenshots and coordinates and item details here on MMOOwned showing the various shops in NR that carry the useless but interesting items. What I've found so far are the toyshop, the keg vendor, the cake vendor and the flower vendor.
I'm hoping there are a lot more and haven't been able to find anything online so I thought it'd be useless, but neat to make a guide for this. Can anyone list any locations and names for any of these other vendors/shops?
Thanks
