TLDR: yes, it's a great way to get kyc-free sats.

Longer version: purse has earners and offerers. Offerers post offers containing the items they want from amazon and an amount of bitcoins they are willing to pay someone to order them and ship them to the offerer. Earners browse these offers and accept the ones that offer a decent number of sats.

When an earner accepts an offer, purse shows them an Amazon "wish list" created by purse. If the earner fulfills that wishlist, Amazon will automatically send the purchased items to the address listed on the wishlist, which purse filled in using the offerer's information.

When the items arrive the offerer can open a dispute if they didn't get what they wanted, otherwise after about a week the earner gets the sats the offerer offered (which they had to prepay using the lightning network or bitcoin's base layer).
