Minor beef with book dealers

I found three kinds of product descriptions today while prowling the used book shelves at amazon.com for Spanish grammar workbooks.

Exhibit A:

• Comments: Some shelf wear to edges of cover, pages yellowed a bit, otherwise good.
• Comments: Bought but never used. Shelf wear. Shipping from MA.
• Comments: about half the book has writing

Exhibit B:

• Comments: Go with the name you can trust: Thriftbooks has the HIGHEST star rating of ALL high-volume sellers! Read More. Spend Less. Your Satisfaction is Guaranteed!

Exhibit C:

• Comments: minor shelfwear; clean pages Average used book, may have price sticker on front cover, shelfwear. BUY WITH CONFIDENCE: 99% Positive feedback. 100% Satisfaction Guaranteed!!!!! Compare our prices and service to the competition!
• Comments: Book shows some use, cover is a bit worn, but pages are clean and book is solid. Some writing in first few pages. A great addition to your library!

It's pretty easy for me to ignore the books in Exhibit B, and some of the books in Exhibit A don't work for me (I prefer a workbook that hasn't already had someone write in answers). The listings in Exhibit C annoy me.

I already am comparing the prices. I think that's why Amazon puts them in order. Buy with confidence? Well, maybe now that this is in all caps, sure. A great addition to my library? How would you know? I just want pertinent information, damn it, but these listings leave me doubtful.

"Average used book, may have price sticker on front cover, shelfwear" and "Book shows some use, cover is a bit worn, but pages are clean and book is solid" look like boilerplate, so I am skeptical about "clean pages" and the second listing's bit about "Some writing in first few pages" makes me think "pages are clean" is maybe not accurate. Just possibly.

Grumble.
