Thanks Mel, I actually have a pre-loved baby goods business and someone asked me if I would buy some from her to sell in my store, but I'm absolutely clueless!

No worries Nelle, I was feeding while I read your reply LOL! Thanks for letting me know about the site. I suppose it's hard to tell because you can't view completed listings to see what price things sold for. It gives me a rough idea though.

I have someone who wants to sell me 3 hemp BBHs and 3 bamboo ones, apparently they have barely been used as she didn't like them herself. I have no idea what a reasonable price to offer her would be...I need to factor in my profit too...
