When the number of "Paid Days" on the IKBA site falls to 150 I tend to add another 30, which costs 9 dollars and 99 cents.
I inadvertently let the Paid Days fall to 140 this time around before topping it up, the price today being £8.35 sterling. Sorry.
It did strike me, though, that this is the fifth or sixth time in succession that I've coughed up. Does anyone else fancy the fun of having a go next time? Just askin'.
