We all know that Costco/Sam's Club have given free passes to military for the duration of the Military Shutdown (while the commissaries are closed). While BJ'S hasn't officially joined the party, they do have a free 60 day trial pass that you can sign up for. To sign up for the 60 day free trial pass click here. This offer is normally invitation only but they have opened it up for the public.
If you are interested in joining BJ'S for longer than 60 days you can sign up for their Military Discount Membership (30% off)
Here are the Details:
Military membership is $35 (regularly $50)
They will also send you a $10 Coupon in the mail.
The offer is valid to both active and retired military personnel. In addition you get a Free Second Card and additional users can be added for $25 each. Note: Military Members must present a valid Military ID at time of enrollment at the club
