If you collect lots of small things with a relatively low value, you might end up paying as much for postage as you do for each item. You should take these costs into consideration when you make your bid. Another good strategy is to always buy a few things at once from the same buyer, as they will almost always offer you a discount on the postage.

When you’re bidding, you might notice that some auctions go more slowly than others, going days at a time without any new bids. The next email tells you how to take advantage of these ‘slow’ auctions.
