This store is awful. Bought a new mac monitor here and cables to connect to a mac pro that is a few years old. The knowledge of the staff was horrendous, was sold the wrong cables the first time and had to return them, was then sold an adaptor (which was very over priced) and it turned out to be faulty and had to argue to get a refund. Don't waste you time even walking in the store.

Efficient. Competent. Friendly. helpful. Took my computer in for repairs, updates etc a few times over the last couple of years and have found the staff to be knpwledgable with Apple products and very accommodating. Even threw in a few freebies with my updates.

Macs have this wonderful cult following. They warrant a price premium because they do most things better than the alternatives. When it comes to replacing peripherals, it can get pricey.
When my power adapter conked out, I went to the My Mac store in Melbourne. It's centrally located and close to my office. The staff there were quite keen to help me. I brought my machine in and hooked it up to the in-store adapters to make sure I didn't have a hardware problem. When that was sorted, I went to the checkout to pay. That was when I found out that they charged a higher price than if I went to the online Apple Store! Prices are high enough but I didn't feel that they could charge an even higher price. I left without it, called another store (who charged the same price as Apple online), bought it from them.
I'm not sure why they needed to be more expensive than they needed to be.

Approximate cost: $129
