Are there any lessons on the different concepts of 'save/saving'?  For example, You can 'save' money at the store when things are on discount; you can 'save' money in the bank; you can 'save' youself the trouble of doing it yourself; you can 'save' for a rainy day... etc.

these are the characters that come to mind... (but I am not sure under what circumstances each are used, or if there is an easy way to remember each)

攒（钱）also 攒够了

积攒

节省

Thanks for any help!

Example sentences -

I am saving up to buy a house.

I have $10000 saved in the bank.

If you do it in order you will save time.

I want to save it for a rainy day.
