The customers have already done it for themselves. And even the satisfy part often is bogus. There is no other online business so notorious for come-ons, promising great stuff and then, after they have your money, delivering much less. There also is no other online business that generates more complaints to local consumer affairs agencies, credit card companies, and even legal authorities. Links are hard if not impossible to find.
Nothing is standardized.
The pages are full of ads that go on forever. It is virtually impossible on many sites to find the exact link that takes you to where you actually want to go. You don't get a lot of choice how you want to pay. Most of the time it s just VISA or MasterCard. And I have yet to see a site that would allow me to fax my payment.
