I've just started selling on Mercari again and I'm curious about shipping. Most of my pieces are fragile and well packed. I'm entering the dimensions and the weight through Mercari and I'm finding UPS is usually advertised as cheaper than USPS. 7.99 flat rate often through UPS from one US city to another. Do I trust that?

So, as a buyer I am searching terms such as Mexican clay. And things pop up in the listings that say Ad. Is that because the seller paid for placement? Curious. Also, when looking at an item it tells me to click on Like for special deals. I did that on something I wanted to buy and didn't see any special deal.
