interest free credit transfer is not quite actually what you think it is.
i took out an 18 month interest free credit transfer last summer. i then proceeded to pay of some of the amount by making regular payments each month, but here is the kicker, i also used my tesco credit card for some tesco shopping each moth, i paid the shopping off in full every month plus an extra £250 to reduce my interest free credit transfer. I noticed each month there is a small interest charge only a few pounds. i asked tesco bank and they have written back to say that as the interest free is still outstanding i must pay interest in any small purchases on my tesco credit even though i pay it off in full every month. So from this month i will no longer use my tesco credit card to make purchases as i will pay interest every time. You have been told. i have a letter from Tesco bank confirming this.
