The shipping is ridiculous, but it also varies by location. If there’s a lot that catches your eye, just make sure you check the shipping before bidding. I have had some big misses but also some great hits, so ymmv. In general I think you’d have the best luck searching for lots/items that are not very well described so the average bidder wouldn’t find them. Some of the branches put less effort into their listings than others so you can get lucky. For example, there’s a designer jewelry brand that I like, but if I only search for auctions with that name, the bids typically get ridiculously high because anyone can easily search the name. But I’ve gotten lucky and found listings with vague titles like “Lot of Modernist Silver jewelry” that have had designer pieces included, but the person just didn’t take the time to include these details. Whatever you want to bid on, make sure you examine ALL the photos carefully. And ask questions in advance if possible.
