When people buy things online and then send them back, it's not good for stores because they lose money.
To keep people happy and make sure they want to buy from your store again, you need to make sure they're happy with what they get.
One way to do that is to make sure they get their stuff quickly, so they don't get frustrated waiting.
Another way is to show them exactly what they're buying with clear pictures and descriptions, so they know what to expect.
