50% off your first Bargain Box with code save50 - I think this might also work on any of the My Food Bag range of subscriptions. You can cancel any time, so a great deal for one delivery!
This also works with referral codes for an extra $50 off! (though 50% comes off after the $50 is deducted)
Edit - it looks like this is only working with referral discounts if you already have a referral discount on your account prior to signing up for this deal. Sorry for the confusion!
