Majority of your 4 ref links are young. Possibly because they sell fast. I honestly also don't feel that one link at 4.33 is gonna keep it from being 4-4.33 refs. May I suggest resuggesting with a more conservative price change?

From what i see at the 4 ref links some appear to be sold fairly quickly and those who don't seem to be poorly bumped :T
