A price too good to be true, usually is.
If you've ever searched for a product on a shopping engine (such as Priceme/Pricespy) you may have asked yourself, "Why are some stores charging so much less than other stores?"

Our customers often share these stories with us, so we thought we would share a few with you, in hopes that you don't fall prey to any of these unscrupulous sales tactics.

  • Goods may be grey market/parallel imported. They may state that the product includes the manufacturer warranty, but not tell you that the warranty is valid only in Europe, Japan, or South America, and NOT in NZ.
  • You may be asked to buy an expensive extended warranty. In many cases if you do not purchase the warranty, your purchase will be denied. (The product is now out of stock, your card does not go through, etc.)
  • Included parts may be sold to you separately. Some resellers will open boxes and charge extra for parts that are normally included by the manufacturer.
  • Hidden charges which don't show up until your credit card statement arrives, these charges only show up when your credit card statement is sent to you.
  • When something goes wrong, faulty, late delivery, doesn’t matter how many times you try to email, they don’t get back.
  • There are so many scamming online sellers today, “buyer beware” protect yourself!

Concerned About Fraud?

The internet has become a more popular source for online shopping, regrettably we have seen more and more instances of fraud affecting online shoppers. Companies trading under many  different names, loading warranties and charging for them as extras when often they are included from the manufacturer. Parallel imports or personal imports where the NZ supplier refuses to repair when things go wrong is often alarming to the unsuspecting purchaser. Inflated freight charges, customs and GST at the border are often forgotten as a buyer is tempted by a lower price. Constantly we hear all these stories, once bitten it’s all to late looking for that refund or replacement. The stories are outrageous at times, customers from Trademe and ebay with no place to turn, time consuming and very frustrating….

So how do you protect yourself from online fraud?

  • Buy from an authorized reseller. If you are at all suspicious, contact the manufacturer directly and ask if a company is authorized to sell their products.
  • Make sure you get a company invoice with GST clearly marked.
  • Make sure you buy from someone who has a phone number and an address on their website, not a P.O.Box number
  • Read customer feedback, you can usually tell if it's genuine or not.

We hope that you will become our next happy customer. And we promise to offer you superior service before, during and after your purchase.
