Hello,
Just noticed that BidSlammer isn't bidding/sniping for me on European eBay auctions, like item #203497605274. I checked a couple of other completed auctions. Yes, I apparently was outbid but BidSlammer doesn't appear to even have bid for me.
My guess is that BidSlammer only works for USA auctions. Is that true? If so, then I wish it wouldn't accept a European auction number. That way, the bidder would operate under no false assumptions that he or she may win that auction.
BTW, in case you ask or are wondering, yes, I confirmed that I, in fact, can bid on European auctions. I placed a bid on one today.
Thank you.

Hello William,
Thank you for your question about EUR auctions. We support all eBay sites and countries. Your bid for 203497605274 doesn't show in eBay's bid history because at the time we placed the bid, the current price was already much higher than your bid.
In other words, you bid 19.00 but your bid had to be 26.50 plus a bid increment in order to show up.
Please let us know if you have any other questions, or require other assistance. We are happy to help.
