Amazon FBA sellers – 3PL/third party storage solutions?

Hey all

Been selling in my spare time and lately business is slow – trying to sort out pulling half my inventory out and wondering if any of you have trusted 3PL options. I’m worried about the Amazon labeling side of things – some of these places I’ve called seem to not really “understand” Amazon FBA and the requirements to send back in.

Anyone know a good 3PL for Amazon FBA that’s reasonably priced?
