The Remember This skill for the Amazon Echo is an excellent list generator for doing up my weekly shopping list.
I use it as a throw away weekly list - adding items through out the week and then using this list to check my final shopping list that I use when I go shopping.
Disabling and re-enabling the skill after the weekly shopping, gives me a fresh new list to start the next week.
Deleting items by number in the list (if not required) I find is a lot more effective rather than trying to get the voice recognition to recognise the item I wish to delete.
Very easy skill to use: aDD item, Delete item, List, Help, and stop or Goodbye.
