You can't beat the convenience of a credit card. If you can avoid the trap of spending more than you earn, the cards become a great convenience. If you spend more than you earn, they become a wicked financial trap. I strongly suggest not spending more than you earn.
The following is a list of web sites offering various forms of charge cards.
Lexington Law Firm (merchant profile) - review Lexington Law Firm can help you remove incorrect or misleading information from your credit report.
PayJunction (sales.payjunction.com) Trinity Credit Card Processing - Merchant Accounts. Trinity is one product that can process credit cards: At your office, through your website and on the go wirelessly.
OptOutPrescreen.com (www.optoutprescreen.com) This is a site by Experian, Innovis and TransUnion which allows people to opt out of credit card offers. I really dislike getting prescreened credit offers in the mail as I worry that a mail theive might steal my identity.
