|Gift Card Bookmark|
One reason is that, as you probably know, credit card companies can get antsy when they see small charges like that as it can be a "tell" of credit card theft. Another is that it makes it easy for me to set my Kindle reading budget.
Amazon makes it really easy to get a gift card - they have eGift cards which are the fastest kind to get for your own use - you get an email gift certificate right away. If you are giving the gift card, and need it today, they also have Print-At-Home cards. If you can wait one day, they have some cute Mail gift cards with free one day shipping. I have one pictured at right - it's a gift card bookmark.
If you want to avoid using a credit card online at all it's easy to get a gift card at a local retailer, specially at a warehouse clubs which typically have them a teeny bit lower than face price.
Have a great start of the work week!
