Hello! I sell these cute little plushies. Each plushie comes in a special gift box. Unfortunately the box makes the shipping a little bulky. So if a customer orders more than one plushie, the shipping starts to get a bit pricey on my end. I want to set up a shipping profile that will allow me to charge more if a customer buys multiple plushies. For example, if a customer orders 1 plushie, it’s only about $6-$8 depending on their location. But if a customer orders 3 plushies, the cost goes up to $17, as I use a usps flat rate box for multiple plushies.
How do I go about setting up a shipping profile for this?
