I hate complex return policies, so I've replaced the generic, wordy, clear as mud policy that used to be here with this:
Just like growing up, shopping for kids can be tough work.
If you’re not 100% satisfied with your order for any reason, please email me at firstname.lastname@example.org and I'll make sure you're happy. Period. Full stop.
No messing around, no pain, no fussing, no crying, no haggling, no arguing. I promise I'll just make sure you're happy. That sounds like a good return policy to me.
