"How much is it", is this sentence for buying one item?

[kwfine]

Dear teachers,

I went to a convenient store for some chocolate, potato chips and some soft drinks for the coming weekend party,
and when I was going to pay for purchased items, a question came across my mind:
Can I use "How much is it" to ask the shop assistant how much I need to pay for the items?
Since I bought more than 1 item, I wonder if "How much is it" can be used in this case.
Or shall I say "How much are they?"

Please help teachers.

Thank you

Kitty

'How much is it?' is possible, though 'How much is that?' is more natural, in my opinion.

"How much is it?" is possible, meaning "How much is the total?"

How much does that come to?
How much do I owe you?
How much for that lot?

To be honest, I wouldn't expect to have to ask a shopkeeper "How much...?" They should simply tell you the total price once they have put everything through the till.

But 'How much is it?' is not unknown. It is the basis for a joke about an author in a signing session in Australia. Someone asks this question (with the appropriate accent for that particular stereotype) and the author writes 'To Emma Chizzit'.
