Tie Breaker
When you check YES your bids will be increased (1) increment only if necessary to break a tie.

Limit
You may bid on multiple lots without exceeding your budget...just place a TOTAL LIMIT for all of your bids...when that amount is reached no further bids will be executed.  TOTAL LIMIT does not include the 12% commission.

"OR" BIDS
When you want only one of several lots...bid on all such lots but place an "OR" between.

 

AND SO ON AS APPROPRIATE
