I have. I don't advise it. I had a stack of cd's I no longer wanted and sent them to decluttr. I had two orders that totaled $10.81 and $7.48 - not a fortune - but a decent little chunk that was coming into my PayPal.
I received notice that the order for $10.81 was processed and I only received $2.56 because they rejected 9 of my 14 items.
Here's the thing that honks me off - the 9 they rejected, they don't ship back to you. I didn't check it (okay, shame on me) but any item they reject, they "cannot return to the seller", which means they got 9 free cd's from just me. Not to mention, I feel like they owe me $8.
All the rejections were not for the discs being beat up - they were "wrong barcode" - which is stupid because I scanned every barcode with the app that they designed!
Seriously, I feel like I would have been better off just giving them away on Facebook or throwing them in the trash.
