When was the last time you revised your return policy?
Hell, when was the last time you even looked at it?
An eCommerce return policy is often an afterthought when building your website. “Oh crap, we need a return policy! Let’s just generate a generic one and put our name on it, it’ll be fine.”
If you’ve done this (and don’t worry, you’re not alone - I did it for three of my online stores) you’re leaving money on the table.
