Jas-G:
So are prices that much cheaper as soon as you sign up with a card company or it that built up over a period of time ?
Over time mate, you can`t start bullying them from day one, its takes time to gain an advantage over them 
You need to get as many cards as you can, and start playing them off against each other, you need to stay squeaky clean payment wise, NEVER miss a payment, never wobble with themā¦
Be prepared to bluff, and be prepared to bite the bullet and go with a card charging more for the week, or with a crap repayment termā¦stick to your āplanā, and try and get a working relationship with your āaccount managerā
