My current returns policy, is as follows.

Items may be returned for any reason so long as they are returned within 30 days of receipt in an unused state, and returned in original packaging, so that it gets back to me in the condition I sent it to you in.

I will pay reasonable return postage costs.

On receiving your item, please check it carefully and only use if you wish to consider using it as I regret that I am unable to accepted returned used items.

This is a fairly generous returns policy, as in effect I am offering most of my items as bespoke, and my understand of the distance selling act is that bespoke items don’t necessarily need to offer this. If it is misused, it may be reduced.
