how to ask for a price match in Japanese?

What is the correct Japanese to use when asking an employee to match the price of a competitor?

For example when I want to buy a TV, I show the store employee the cheapest price on kakaku on my phone and say "この値段でおねがいできますか?"

How would a native Japanese speaker ask for this?

You can get the store to do price matching only at certain stores - where they (usually) advertise that they do it, such as home appliance/electronic chain stores... and if you are showing the price at a competitor on the screen, yes, you can say that to get them to price match.

Things to look out for would be:
最安値保証 (lowest price guaranteed) “sai-yasune hoshou”
最低価格保証 (lowest price guarantee) “saitei kakaku hoshou”
プライスマッチ (price match) “puraisu macchi”

You can ask them first if they provide that (generally):
Sai-yasune hoshou shite imasu ka?
Or
Puraisu macchi site imasu ka?

Then if they say yes, you can show the price from a competitor (not just the list on kakaku.com, but the actual competitor’s shopping page would be more useful).

thank you AK

"you can show the price from a competitor"

what should I say as I'm showing them the price from another store? I know they'd understand if I show them silently but I imagine a native Japanese speaker would say something.

この価格にできます？ (Can you make it to THIS price?)
Or
この価格にしてもらえます？(Will you make it to THIS price?)
… would be something I’d say :)

thanks AK!
