Dog walking or other skill based teaching/tasks. You might need some small things like poop bags or something else. In the past I did dog walking & that is easy to start. Then I expanded to helping train & other tasks around taking care of dogs. That’s just what I did but you can choose something else you like such as music lessons.

I think there is some more nuance here then all restocking fees are bad. For some businesses that sell items that are custom made or have so many varieties that they are practically custom parts. So when an item like this is returned it can’t be sold at the same amount & storing the item until it sells has a cost. So to encourage customers to be certain of their orders a restock fee is used on some items to stop customers from ordering testing then returning what they don’t like.

If you bring up Amazon’s restocking fee your right those guys are assholes who try to squeeze as much cash out of everyone.
