The LV section of tpf is very active, probably even more than Coach. You can get bags authenticated here:

I've seen a few LVs at thrift stores, some of which might have been authentic, but I didn't want to take a chance. You can't assume that an auction starting at .99 means a bag is fake. Because these bags are so popular, sellers figure there will be plenty of bidders. About a year ago, ebay encouraged sellers to start auctions at .99 because of their fee structure. That has since changed, but many sellers have kept the format because it worked so well. Often starting an auction low ends up with a higher end price because it generates a lot more bidders. It only works well for popular items though.
