What are my consumer rights if a price decreases? (Australia)

I thought I would answer a question that I had recently, where I purchased and paid for a product, and then only a week later the product went on sale for lower. Unfortunately, there are no statutory consumer rights if the price decreases, unlike those for manufactures warranty, acceptable quality and fit for purpose. But thankfully, a lot of stores have very favourable return policies.

Many stores allow you to return a product if you simply change your mind, for example Ikea (WA) has a 90 day return policy, Super Amart a 30 day return policy, Big W a 30 day return policy on non-electrical items, Officeworks and Bunnings don’t have any time-limit on their returns. These are only a few examples. Now, generally, if stores offer these return policies, they generally understand that if the price decreases within this period, you should be entitled to a refund in the difference in price.

The reason for this is there is nothing stopping you from buying the product at the discounted price and then returning it on the older receipt with the higher price. The stores would probably prefer this as it means they get a returned product in original packaging.

For my recent transaction, after the store said they could not do anything about the price reduction, only when I explained I wanted to return the item and buy it at the lower price, they got the picture and put through a refund of the price difference.


How to pass the PMI Project Management Professional Certification PMP exam

Having recently passed my PMI PMP exam on the first try, I thought I would share my thoughts on how to also pass the PMP exam.

The resources

The resources I used were quite limited.

  • PMBOK – I read through once very early on when I was completing the 36 hours of coursework and never used it again.
  • PMP Exam Prep by Rita Mulcahy, was a key resource, and I’ll explain more on that shortly.
  • The PMP Exam: How to Pass on Your First Try by Andy Crowe, another key resource and very easy to read.
  • Head First PMP, Book by Andrew Stellman, an online recommendation with the other two resources, but I didn’t like the graphic format and didn’t get through the first chapter.
  • PMI PMP Exam Prep by Pocket Prep, Inc. android app, I used this more as a motivational tool and training reminders.

The questions

The PMP questions are all situational, and in my opinion the practise questions in the above resources a lot easier.

  • Plenty of network diagrams which were easy marks
  • Plenty of basic Earned Value questions, like given PV, EV and AC, what is the status of schedule and budget.
  • No ethics questions.
  • A lot of change control management questions.

The learning

Instead of memorising the process group and knowledge area map, I should have been memorising Rita Mulcahy’s process diagram. These would have helped significantly in the situation, especially for the planning domain which I was Moderately Proficient.

thydzik’s MAME cabinet update

After over a decade and the MAME cabinet collecting dust, I decided to rejuvenate my MAME cabinet once again.

First to go was the 26″ KORTEK color monitor, which was roughly 30 years old. I stripped out all the legacy IPAC and JPAC harness and went with a basic USB arcade decoder, the USB to Xin-Mo Arcade 2 players with 30 inputs.

I found the Asus VW266 26” Widescreen LCD Monitor, which was the perfect width for the cabinet.thydzik-mame-cab-2016-update

Fix fading red (magenta) toner on HP Color LaserJet 2600

My HP Color LaserJet 2600N printer recently experienced the infamous faded red tones, this is due to the magenta toner being positioned at the bottom of the unit and the optics being the most susceptible to dust and debris.

Hyundai does not recommend an engine flush during routine service

I recently had my Hyundai Tucson services with the Hyundai authorised dealer recommending an engine flush, even prior to inspecting the vehicle. An ‘engine flush’ clears the gunk out of your engine by pouring a chemical into the engine and idling. Due to the use of chemicals, it can possibly be damaging to modern car’s engines.

I was concerned due to no mentioned of an engine flush in the Hyundai Recommended Maintenance Schedules, so I contact Hyundai directly, this was their response:

I have been in contact with our technical department both locally and overseas and they have advised that Hyundai don’t recommend an [engine] flush at service.

Review of Perth Premier Studio (premierstudio.com.au) and their dishonesty

In March this year, my dad excitedly let me know he had won a “Premier Photographic Experience valued at $500″ from Premier Studio (premierstudio.com.au) by entering a competition in the HIA Perth Home Show. Given I have two young daughters, he was looking forward to getting some family portraits of them for his home. I took it on board to arrange a time suitable for all of us.

Within a few days I called Premier Studio to see what $500 worth of photography would get us. The voucher already mentioned a weekday appointment would cost $100, with a weekend appointment costing $200. I was happy to take a day off work to make the most of the voucher. For some reason Premier Studio were extremely hesitant to disclose what could be purchased with the voucher.  Stating my dad had to call and get a personalised package, as it depended on where he placed it in his house, over the couch or television.

It was only at the end of the call that Premier Studio mentioned $350 is the price of their smallest framed photo (10″ by 8” if I recall). I mentioned this to my dad and we agreed a nice photo of the two girls would be ideal.

I was aware that my dad had to be present since he had the voucher. I thought I would take the girls with him to get the portrait, leaving my wife home to get some time to herself and a chance to study. When I called to book the appointment with Premier Studio, things took a strange turn. Premier Studio insisted that the whole family needed to be present, I mentioned that it was difficult due to a full car already, but they insisted that these were part of their terms and conditions. I mentioned that I didn’t remember previously reading about this. When I got home and reread the terms and conditions, I noticed Premier Studio added the additional terms. Below is a screenshot of the additional terms (they also took the opportunity to fix a spelling error).

Premier Studio T&C’s March 2016. View the old T&Cs here.

Premier Studio T&C’s April 2016. The addition of “Premier Studio reserves the right to refuse service if the entire family does not attend the photographic shoot. ”


After Premier Studio changed their Terms and Conditions, we decided we didn’t want to deal with this dishonest company.

To not disappoint my dad, we ended up taking our own photos in Kings Park. My dad is very happy.
