10 bids from the same bidder. Current bid at 99p.

It still has 6 days to go. Why would you bid 10 times at the start? Seems odd. Has feedback of 300+ so should know what she or he is doing. If you wanted something that much to the point of making sure that no one gets it, surely you'd put a stupidl high bid right near the end?

incase anyone bids against them, they must be keen I guess?

Not everyone is sensible enough to bid in the closing seconds.

It depends. Many people use auto-bidding software, which goes against ebay terms. They may have done this unintentionally, or they could just be bidding lots at the start. As long as you get the sale you want I wouldn't stress it.
