Buy Insider Now or Wait?

M12 Insider with H/O 2.5 battery for $300. I know earlier this year they had this combo with the H/O 5.0 battery for the same price; so my question is should I buy this right now (am I getting an okay deal?) or wait for a hopeful sale in the upcoming holidays. Don’t NEED the tool asap I just really want it for the convenience.
