bloomhjelm I use pirate ship for my shipping. I don't know why anyone does the flat rate USPS boxes TBH. I buy my own boxes in sizes that make more sense for my packages from SupplyHut and even with that added expense, pirate ship is MUCH less expensive than flat rate prices. I can choose from different USPS rates as well as UPS.
As far as shipping charges go, I set mine up to charge a flat rate plus $1 per item. I make sure my shipping charges cover all my packaging materials and my handling. I learned in my previous business that if I don't get paid adequately for all the tasks involved with my business then I will burn out quickly. I used to do a lot more shipping and I charged exactly my shipping prices to my customers thinking it was a selling point but I was selling myself short and when it came time to do that shipping I HATED every minute of it. Now, with dahlia tubers, it takes me a long time to get those orders out but I'm being compensated for my time so I honestly don't mind it at all. I work long days, order take out for the fam for dinner a few times, and catch up on podcasts. š
