It's the computer shop that same as all other computer shops.
However, it was interesting to note that the dude behind the counter was very willing to match prices for me. All I had to do was mention a place and he'd more or less accept my word... more based on his judgement and experience than that I'm just a very trusting guy.
He also said to come see him for any prices matching and they'd be happy to assist.

Approximate cost: $good
