Am i the only one who feels like there should be a way you can transfer your left over RP into IP? I mean really, what are you going to do with less than 160 RP(the least expensive boost)? I think that there should be a type of transaction to switch your left over RP into IP just to help us use a little more of the hard earned money we spent on the RP.
Leaving money on the table or in our Xbox Live account makes most of us a bit uncomfortable because it feels wasteful. Hal Arkes, who pioneered the study of the psychology of waste, theorized that this is a holdover from what’s called “the sunk cost effect.” This is when not losing unrecoverable money you’ve already sunk into a losing proposition becomes the main justification for throwing new money in.
Which basically means NO.
That's also the reason when you ask the support for 4 RP they will give you 130.
