Most of the time I sort by 'ending soonest', then start on page 1 and work my way from there - this way, I won't have to go through a long and agonizing wait before I find out if I win or lose. I also don't have to bother with auctions that end up way overpriced (or just out of my league). I hate searching for a model, fining a good one really cheap with several days to go, add it to the watchlist, then, as it resurfaces near auction end, find that the price has gone from great bargain to ridiculously inflated.
The downside is, of course, that sometimes there's very little time to react/decide. It's also not possible to 'ask seller a question' when there's just minutes to go, but that doesn't really bother me, since I generally avoid such auctions anyway... I mean: if 9 sellers out of 10 can list the shipping costs from country A to country B, then why can't #10? Same with condition: if you're trying to sell a model at above average price in (presumed) above average condition - show it! If your photos are so lousy, it's impossible to see the condition, it's just not good enough, and you need to try again, and again, and again... simple as that. "Nice toy car" is also not a very good description, especially not if you consider, that a simple look at the baseplate would most likely reveal lots of relevant data. I'm really tired of sellers who can't be bothered to spend more than 10 seconds per auction - they rarely get my money!
Buying form Denmark, I also use ebay.co.uk as my 'base', but mostly I have preferences set to show auctions from all of the EU. "Worldwide" I rarely bother with, mainly because of import duties and possible long delays in customs.
Like others, I also use an autobidder and hardly ever bid on anything in advance. I can't see what good it would be? Simply raises the price.
I hardly ever bid on auctions with more than 5-6 bids. It may have started out as a good bargain, but 'the bird has flown', the secret treasure has been discovered by the rest of the world... too bad, but maybe next time. Also if there are many bidders, chances are, that one or more of them are desperate to win, so even if the price still appears resonable, there's a hidden, very hig, max bid.
More strategy? Hmmm... I generally avoid the angry, bitter sellers - you probably all know them... "if you're not happy with my terms, don't bid!", "due to some stupid people, I no longer...", "don't buy from me and then give me less than 5-star ratings for postage" - For a seller to be so angry, some disputes must have taken place and you know the one about "smoke without fire"
