Wallet is in my purse -if I have more than a hundred dollars in there, I fold it up and put it in my bra, towards my armpit, sometimes in my shoes.
When I do carry one it is in my front right pants pocket. When traveling I rarely carry one and just have a small id type folder with a credit card, 20 bucks and driver's id.
I will at least enough to make a few dollars when I sell them.
In my opinion, simply put: "The seller places a price on the item he / she thinks the item is worth." "The buyer will determine what they feel the value of the item is for them.".
