Is it above board to offer bonus items or free postage with Buy it Now?

Hi, I am having a clear out due to downsizing of my home. I have quite a bit of things to sell and really just want it gone. Its is above board/kosker/okay? to have bonus items as an incentive for potential buyers to buy? I am not 100% sure this is the right thing. Please no negative replies. Thank you

You can offer bonus items provided you meet certain requirements.
