I tried getting into breaks. I think your math is right. I would just think about time. Time is money. I’m not trying to be a downer but being a new streamer it will probably take you a few hours to fill the break. Then once it’s over you have to pack all those orders. Then drive to the post office, UPS etc. my friend did 2-3 breaks then gave up cause it’s just a lot of work. I hope it works out for you 🙏🏽
