So I've already read some posts about people saying that in a book deal they got books in a book deal that weren't postable. When I got a 3 for 1, the book I actually requested was in impecable condition. But, the two that were also off of the user's shelf, were ...older than me and lets just say well loved. I reviewed the rules for the condition of a postable book and I guess it meets those standards...but  I'm really quite dissapointed.

The book covers are tattered and worn, the spine has seen better days and the pages are seriously yellowed.One of the books is rather thick and the spine is kinda slanted like it was put under stress.  Again, like everyone else, I feel like a cad even trying to mention this to the user.  I dunno...what do you think?

Since the book you actually wanted is in great condition, I probably wouldn't say anything about the ones you received free.  But that's just me.

Well.. this is definitely a grey area since the conditions guideline is subjective.  Even if a book doesn't have any tears, water marks, etc it can still not meet the conditions... when you post a book remember you have to agree that a book isn't "excessively worn".  I had a similar issue where I did a 3 for 1 deal... 2 of the books (including the one I requested for credit) were in great condition but the 3rd was as you say well loved.  I am also a bit picky about my books and was definitely disappointed.  I definitely felt the book was excessively worn but didn't want to really make a fuss either. 

I wouldn't mark the books RWP OR ask for credit back since it was a deal.  However, I would PM the person before-hand, mentioning the condition and that the person may want to be a bit more careful with the books they post since others may feel it is excessively worn and therefore mark the books RWP. 

I always try to take into consideration the publication date. I have just discovered an author I really love (Dorothy Uhnak) but all of her books were written, seriously, before I was born. A few of them were reprinted in the 90s, so I tried to request those ISBNs. But, with about half of them, they weren't ever reprinted so I knew I was going to be getting really old books. The covers are a bit worn, and the pages are very yellow, but no mold or musty smell, so I can deal with it.

In this case, since you spent one credit to get one pristine book and two that are quite worn, I wouldn't make a fuss. But, a polite pm to give the sender a head's up that others might be more picky might not be a bad idea.

Yellowed pages are completely normal. I love books, and sadly, paperbacks are subject to all kinds of stress. I try to be gentle with them, but even with gentle handling, not all books are created equal, and a slanted spine could just mean it sat under other books and the weight made it tilt that way.

The cover thing... i think it depends on how well worn they were, and how tattered.

I think since you only put out one credit, then you could be lenient this time. If they are very old, then they've probably just seen a lot of life. I remember when i was a kid and i'd borrow my mom's books... some of them had covers in very loved condition (i think of butter when i think of her books not because they were greasy or anything but because the covers were so soft feeling if that makes any sense), and when i post books, i try not to post such things, because i am not sure where the 'excessively worn' line is. There was a day when i'd read anything with all its pages. I probably still would if it promised a good read.

I love books and I love old books. I even put a reader's condition that I understand about old paperbacks and have lower expectations. Just like with us folks' faces...

Mass market paperbacks get reading  lines down the back, that is not excessively worn. Now, a cracked spine is, and shouldn't be postable.
