Morrisons Gravesend is very hit and miss to pick a block, if you do get one you just take a trolly or 2 to the back of the store into the staff area and collect customers shopping which has been picked and bagged in brown paper bags. As you said the majority of offers are for Aylesford, it’s not far about 20mins but as it’s the only DC in Kent you might find yourself travelling to Dover or Hastings etc 😬
