Does ebay push your maximum bid up in increments?
IE: if the auction is currently at £100, the other guy has a maximum of £200, and you put on a maximum of £210.
Does ebay test the water in increments Like £110 = fail, £120 = fail, £130 = fail etc right up to £210 which would take highest bidder. Because if it does then that looks like what happened above. The time stamps between the bids seem pretty close together.
