Your definition of a mail order bride is wrong. What you "pay for" is the information to contact men or women, and yes, there are companies which introduce women to men. I will explain the basic process. First, you contact an "introduction agency" and request some information. This is no different that signing up for a fee-based dating site. Then the company sends you a basic "catalog" which contains pictures of women and their basic information, but no addresses, phone numbers, etc. If you are interested, you pay their fee and they will then send you a full catalog containing the names, profiles, and contact information of women. Never do you "buy" a woman and the woman is free to either accept your "attention" or reject you.
My uncle, for example, also paid extra for a video containing the girls speaking. There were probably 40 girls on the video. (This was the early 90's). To be honest, he liked 3-4 of the girls, but couldn't make up his mind. It wasnt until my mother pointed out that one of the girls had safety pins holding her shirt closed, had needed to borrow a hair brush, and that most likely, she was wearing her best clothes. My uncle, who had grown up dirt poor, picked her. They wrote for nearly a year, then, he travelled to the Philippines. When they met, he was never allowed to be alone with her. Her mother always sat between them. Then, they married. He didn't "buy" her. But, as is custom, even among Filipinos, the groom pays for the wedding.
Between airfare, hotel (he stayed there for a month), wedding, souvenirs, etc (plus being forced by the RP govt to open a bank account for his wife, should the marriage fail), he spent a little over $15,000 for everything. However, not one penny went to her family.
