riddle - Nine is the limit

My first is in a bank,
My second is an evergreen,
My third is for your benefit
My fourth is in a store,
My fifth is identical,

If you've found the pattern
What is my sixth?

Those definitions might be a bit broad, but there is only one answer that follows the pattern.
If needed, I will add more clues.

This has nothing to do with computer. Each line refers to one word. Words may or may not be in the same semantic field but that's not what is important.

As you, fellow puzzlers, keep to try to make sense of this riddle as a whole, I need to tell you that each definition gives a word but those words are not in the same semantic field nor express the same idea.

I hope this one won't be an easy giveaway

My first is cautious,
My second is wise,
My third is wine,
My fourth happens in the garage,

My fifth is unchanged
Now you should have a better grasp on the pattern
So what is my sixth?

Answer

Your sixth is

sane

because

each word is an iteration of the pattern S A _ E

My first is in a bank, My first is cautious

safe

My second is an evergreen, My second is wise

sage

My third is for your benefit, My third is wine

sake

My fourth is in a store, My fourth happens in the garage

sale

My fifth is identical, My fifth is unchanged

same

Nine is the limit because

there are only three other words that fit the pattern: sate, save, and Saxe
