100% EP bonus: Stop by the bank today and buy either Barnyard Bills or Premium advantages to benefit from 24 hours of 100% more EP! Any purchase of BBs at the Bank, will give you a +100% EP-Bonus on your Harvesting!
as a reminder:
On Mega EP days, if you make a BB-purchase in the Bank, or gain BBs from Cash-for-Action (video watching for example), this will entitle you to Sid bringing you a +100% EP bonus for 24 hours

This bonus is not stackable if you buy 2x BBs during one Mega EP Day.
However, if you already have a bonus active on your farm, this bonus will be added to the one that you already have.
