Low Interest Credit Cards Comparison

Just how low can Low Interest Credit Cards go ?.
I’m always amazed by how it seems that every few days when checking my mailbox I find new offers for Credit Cards sent to me without my request and upon opening them I see they have taken the liberty to fill in my personal details apparently to help me to sign up to these Low Interest credit Card offers. Yeah right ! When they send me an aplication form with an addressed postage paid envelope to return my appication form I always make use of it.
Sure I’m yet to actually fill in a application form but I always use the envelope to return the unsolicited mail to them along with anything else I have recieved in the mail without my request.
