Bundle order canceled (after payment) due to "I'd only get $13 for both items".

okay so I was really interested in a pair of pants. I bought the same pair just recently (like new) only to find they were too small. I just found another pair but this buyer had probably the highest price I've seen for these pants on depop, not to mention shipping was $10. So I sent an offer, but also did a bundle that included an item that I liked, but was listed cheap. The seller accepted my offer, and I ordered. I sent her a message thanking her. A little while later I got a message back: " I saw that you bought a bundle, and it did like an auto thing so I'd have to pay for shipping. And so for those jeans and that skirt I'd only get $13, because of the shipping and random fees. I need to cancel the order. if you want to do the bundle I can do 10% off"....... all I can say is wow ..... It also says on her bio she is a reseller. Way to do business and honor sales!!

Edit to add: she had it advertised in her bio " Free shipping with bundles".... I'm a seller too, I'm also fairly new to depop. I didn't know much about bundling before this. But if this were me I would have honored my sale and let it be a lesson learned.
