So the really cool grocery trailer I bought a few months back has pretty much rendered itself unnecessary. When I got it we lived in a highrise far from many good stores and it was useful for making big shopping trips. It was great as it held a *huge* amount of stuff (3-4x what I could fit in panniers with the added bonus that my maneuverability did not suffer) Now, though, we are within walking distance from many great stores, and a really short ride from others. I don't really see myself needing to use it anymore.
Anyway, I'd be up for trading it for something, or giving someone a good price on it. It's the Wike City Shopper trailer. I got the 20" wheel option,the extra front wheel option (that doesn't work that great, actually), the cover, and the pushbar for the back. All told it was about $450. I probably used it 5 times. If I could get half that or best offer I'd be thrilled. I hate to see it sitting unused in the shed when it could be really useful for someone else.
Photo is below (mine's blue/yellow with red cover. The colour combination makes it look like a child trailer and I've found that drivers give much more space for that reason alone)
