50% MORE SDS on Top Offs

They are offering this deal again! When you top off (add sds) you will get 50% more sds from the amount you will get. I think this is a good idea, but they are only offering it for a certain amount of time, they are only giving us a few days to consider this. I am not going to use this since I dont do top offs, but are you? What do you think about this?
