Mmmh... it really depends on what is rereleased.
Items are released twice a week, Tuesday and Thursday.
Currently, only skelly has been RRed. Afaik, the value has dropped to three Caps by know.
*checks guide*
Currently between 3 and 6+, according to filigrees.
It probably will rise again, once the event is over and the FP cannot be purchased anymore.
Also, it's hard/impossible to tell how fast the value of Skelly will increase again.
Secondly, we do not know so far, what else will be released in the upcoming days. People speculate for the Gold Ribbon Wig. However, chances are, TNT saves this for next year.
Right now, the only suggestion I can give is: Wait until several popular items are RRed, then hold on to them.
If some really popular and well sought items will be offered in the RR-Event, chances are that values can increase.
After all, despite many RRs, NY in FL is currently at 20 Caps. Not much and I don't know how high the value was before, but I'd say it's still a lot.
But no matter what, values will drop and I don't know how fast those recover.
As things are now: No, I don't think it's worth it right now.
In two weeks it might be different, though.
