Here's a story about my stupidity...

I went to the bike shop to pick up new brake pads. I got a chain breaker, too. At checkout, the employee asked if I wanted a master link, too - I said sure, and he showed me how to install it on a piece of spare chain he had. He reminded me not to take the pins all the way off (which I've already read about online.) So I get home and I try to install the master link. I take off the wrong pins or something? I'm not sure what I did, but I couldn't get the master link on. I bent a link a little bit from trying to force the master link on. Ugh, so I'm sitting there wondering what to do, and I see that I already have a master link on this chain I did some thinking, and I added the master link and made the chain so that it's only 1 link away from being able to be connected. But I can't connect it because I can't get the dumb pins back on.

I figure I'll just go to the store and buy another master link, and use that as the last pin to connect the chain. $2 versus the cost of a new chain seems nice. But I didn't even need to buy the master link in the first place >_>

So my question is, is there any reason why I shouldn't have two (soon to be three) master links on one chain?
