What is a good strategy bidding on such items?
Australia : where I bid
there are 2 columns "res" and "bid"
I bid the reserve, if a bid comes in higher, at a later date, I get an email to that effect, inviting me to re-bid.
If there is a lot of interest, I bid at whatever I feel is "my" price, then leave it be
I do not bother at all at auction date,
I log in next day to see result, that way I do not fall to FOMO (Fear of missing out)
