You can skipped any delivery you want up to 3 days ahead of the delivery. So, for a Saturday delivery, you can skip that delivery up until Wednesday 5pm.
Simply log in to your Lettuce Account and uncheck the dates you don't want deliveries for. You can plan deliveries up to 3 months in advance.
If you still want your delivery, but need it on a different day, just let us know at email@example.com and we will do our best to make arrangements for that.
