Ah where to begin? Why the start of course! You may have seen tons of sites floating around the internet selling neopoints but in the beginning there was only one. Neopoints.ca The owner of this site came up with the original idea of creating a safe marketplace for people to purchase neopoints. A fundamental problem existed because there was no trustworthy source people were forced to resort to shady internet deals where they were usually dealing with a person cloaked in anonymity.
This site rose in popularity selling nearly 4 Billion Neopoints however, after a private offer with Burmac Business Systems the domain name was sold and the team from the original site moved to a new domain name NeopointsDeals.
To date they are the industry leader with in excess of 5.3 Billion neopoints safely delivered. The nearest competition has sold a mere 700 million. NeopointsDeals.com employs a wide range of people from mothers on maternity leave to retirees who use Neopets as a way to unwind. Their clientele has included everyone from CEO's to celebrities and they are known for setting the customer service standard with no item being unattainable... all for a price of course.

1) Myth: It must be a scam no one can have THAT many neopoints. Ah while it is highly unlikely that any one Neopets User would have tat many (xxxx is sitting on 6 Billion) sites like ND employ hundreds of people all with either huge stock piles of Neopoints and rare weapons or amazing restocking skills.
2) Myth: The neopoints must have been obtained illegally and will get you frozen! This is generally spouted by users on forums who don't have a clue what they are talking about. Trustworthy sites understand the fact that a return customer is better than no customer at all. Having a customer frozen is a big headache not to mention it removes the opportunity for repeat business!
3) Myth: Those sites are all cookie grabbers! Really? Well to be honest companies who sell neopoints are about 100x more fearful of cookie grabbers than you are. Simply put while you may lose 600k or even a million they stand to lose billions in neopoints they have stocked.
4) Myth: Neopoint selling sites want your password! Absolutely not true. Honest sites will only ever ask for your username and deliver the neopoints through shop, trades or gifting. If a website asks for your password stay far away from it!

Fact: Buying Neopoints is safe if done through a reputable company
Fact: Don't trust any site that offers birthday cracking, avatar getting or trophy sales.
Fact: The very few people that are frozen are usually frozen for other reasons NOT related to buying neopoints.
Fact: The safest place to get neopoints from is from the company that has been doing it the longest we recommend ND.
Fact: If a website asks for your password you probably will get scammed.
Fact: When you buy neopoints it looks just like any other transaction of Neopets. Impossible to detect.

In conclusion it is good to observe a few rules when buying neopoints:

1) Don't buy from individuals. Buy nps from websites instead, individuals have no accountability and due to the anonymity of the web it is not wise. A neopoint seller with a website is showing that they take it seriously and wont scam you.
2) Ask questions! The more questions you ask the better! A reputable company will answer any and all questions you toss their way, customer service is an essential part of business.
3) Buy in bulk! Sellers often have discounts if you buy multiple items at once or will issue you a coupon for say 10% of your order if its large!
Well thats it folks enjoy your neopets millions!
