I've got 20 credits that I'm never going to use because (1) The cheapest credits item is still 40 credits and (2) I can't buy more credits in order to use them.
I bought these credits with TU. And if I remember correctly, the conversion rate was 100k/1 credit.
And considering my bank right now, that's a lot of tu that I'm not going to get back.
So I propose that we can be allowed to "sell back" our credits--at the same conversion rate.
