Sick. What do you usually search to find this stuff?
Just "hockey cards," sorted by auction, ending soonest, and US Only. If it's got way to go before it ends then I'll watch it and check back in to see if I think it's worth bidding on. If I'm looking for someone specific then I'll search "Philadelphia Flyers cards," "player x cards/Young Guns/auto," etc. That's how I found all the Flyers cards and the Vrana.
I'm not sure if the site lets you do this but on the Ebay app you can set a max bid on the item. That way if someone outbids you, Ebay will automatically bid higher on your behalf up to a certain price. So if you set your max bid to $20, Ebay will automatically bid for you until someone bids over $20. You might have already known that but I found it really useful since I had never bid in an ebay auction before last month.
