The thread you mentioned didn't have a reply button, so I'll post here. All of these companies do shops in the US, even though a few companies are not located in the US themselves. I tried to only list ones that offer shops nationwide, but an occassional regional company may have slipped past me. Also, I didn't include any merchandising companies (although there is an occasional company I've listed that does both mystery shopping and merchandising). They tend to be grouped in together with mystery shopping, but when I started my list, I wasn't interested in merchandising, so I didn't include them.
