Isn't slogging through mountains of crap kind of what online garage sale-ing is all about? I mean, if someone else does the work for you, is the hunt compromised? Is the find as satisfying? Isn't it better to earn a deal rather than having one handed to you?
I'm not sure.
Besides that, TLL might not be as practical as it seems. Great items worth curating have a tendency to go fast, and once something has been featured on the site, it goes even faster. I've already experienced seeing more than one great thing on TLL, only to find it already sold.
Anyway. Here are some of my favourite finds, found on TLL just today. At the time of this posting, I think they're all still available.
