I decided to take a look at my transaction archives just for fun, and I noticed quite a few transactions cancelled by requestor within the past month or so.  One poor book has been cancelled twice!  Most of them were cancelled within a day of the request, and I didn't even know they had been requested.  I accepted the other one, and found that it had been cancelled when I went in to print the wrapper.  So, does this happen to the rest of you very often, and I just hadn't noticed it?  Or am I just having a run of bad luck?  This doesn't send up any red flags tptb, does it?  Just curious - thanks!

No, TPTB don't care ... that is why there is a cancel button. In case you change your mind.  As the requestor OR the sender.

It happens. I haven't noticed that it's all that frequent, really. But I've canceled books that I've ordered a handful of times, and had some canceled on me before I mailed them, too.

I tend to cancel more often when the book rolls over several times.  I'm about to do that with one in the next couple of days.  The first person let it go the whole 5 days and I think the second one is also.  I'm going to be away so if it does roll over I'll just cancel and decide when I get back whether I really want to read it or not.  Sometimes I accidently order a book and have to cancel it.  Good luck.

Well, I cancelled one yesterday. I wanted vol 1 but I requested vol 2. I had vol 2 on the brain but for the wrong reason. I was so glad that I could go in and cancel because I really didn't need another vol 2.

There's a delay (an hour maybe?) from the time someone requests a book and it appears as requested to the sender. If the request is cancelled during this time, you'd never know it unless you checked your transaction archive.

I posted a book this morning that I knew was on autorequest on someone's WL (it's noted when they're on your TBR pile) and the request showed up on my account right away, within minutes. I didn't get an email for probaly an hour or so. 

not a lot, but they do seem to come in groups-- maybe people who are looky-loos and can't settle on what they really want to spend their credits on!
