There's a bonus to selling and upgrading during events. However,  this is not set in stone and could change at the next event. During the Robots in the Sky event, there was a x3 bonus on the last day. This was publicized on the mobage FB page. I don't think there was this type of one day bonus for Fatal Furies.
