How many locks do you bring and why

As the subject implies, how many locks do you bring to an auction and why do you bring that number of? Also, if it's more than one, did you get sets of keyed alike locks or ones that have their own key (or combination) each?

One on my person and more in the car. That is usually one more than I need ! 

i normally bring three locks. these days i normally buy 1 unit, maybe two at the most

I bring around 12 cause you never know! Usually only need 1-3 for the day, but about this time last year I went to an auction that some how flew under the radar and only a handful of newbies showed up and no regulars. There were 7 units and I won 6 of them. I had 3 under my belt before the newbies even felt comfortable bidding seriously. 

I usually bring three. Two are keyed alike and the other one is not. Why three? Because any more than that won't fit in my fanny pack. If I buy more than three units the facility managers have been kind enough to put their locks on them for me.
