Sold some old textbooks

Hey, so I finally got around to selling off some of my old college textbooks, like 'Calculus: Early Transcendentals' and a 'History of Art' one. I used SellBackBooks for the first time. It was pretty chill, just scanned the ISBNs, got a price, and printed out the label. Shipped them out and got paid. It was all pretty straightforward, definitely beats having them sit around collecting dust.

Consistent and reliable service

I've used SellBackBooks a few times now, mainly for my engineering and science textbooks after each semester. This last time, I sold 'Linear Algebra and Its Applications' and 'Organic Chemistry'. The process was just as smooth as my previous experiences. The quotes are competitive, and they always send the free shipping label right away. Payment usually takes about a week or so after they get the books, which is pretty standard. It's why I keep coming back, they're consistent and don't make it a hassle.

Good experience selling law books

I decided to sell off a few law school textbooks, including my 'Black's Law Dictionary' and 'Constitutional Law' text. The initial quote process on the website was simple; I just entered the ISBNs and got instant prices. I did have a question about the condition guidelines for a slightly worn cover, so I used their contact form. Customer service responded within a day and clarified what was acceptable, which was helpful. I packaged everything up using their prepaid label. Shipping took about 5 days to reach them, and then I received confirmation of receipt. Payment via direct deposit arrived about 4 business days after they confirmed the books' condition. Overall, a solid service for getting rid of old academic books.

Easy process, quick payout

Sold my old 'Psychology: A Concise Introduction' textbook here. Got a fair quote fast. Printed the shipping label and dropped it off. Payment came through quickly after they received the book. No issues at all.

Anyone know if I can stack a couple of those bonus codes? Got a first-time seller one and another from their newsletter.

S Stephanie Harris 4 days ago
Nah, pretty sure you can only use one code per order. Tried it once, didn't work for me.

Nah, they don't let you combine them. I think it's one bonus code per transaction, gotta pick the best one!

Hey, wondering how long it usually takes to get paid after they get the books? Need the cash kinda soon for next semester's books.

A Amber 1 month ago
I used them a couple months ago, it was pretty quick. Got paid like 3-5 business days after my books arrived at their place.

Yeah, usually pretty fast. I think they do direct deposit too, which speeds things up a bit. Just make sure your books are in good condition, that's usually what slows stuff down if they have to review 'em more.
