ebay always gives me that problem. You want the object, and you only have to bid a little more, and before you know it, it’s twice the price you wanted to spend, and you still lose.
Which is why I only search for items with “buy now” as an option. Some items even let you suggest a price, if you think the current price is too high, or maybe even too low.
ebay’s great (and so are flea markets) since, a lot of the time, the tools need to be spruced up. That makes a great fun project, even on its own!
