This month, the price of the 3D Printer's Auto-off Switcher is now changed to $30 CAD. The original rule is that once there are more than 3 clients who purchased this product, the 4th client will need to buy it for $30. The 5th person will need to buy it for $50. Now, the thing is, the total price of the materials used to make 1 3D Printer's Auto-off Switcher is more than $100. This is why only the clients who purchase the earliest will enjoy a price that is lower than $30 CAD.
One more thing: I know how severe the misinformation on the internet is. This is why I do not want to be one of those who spread misinformation. It is also why I really recommend you to contact me and have me starting video meetings with you, or even meeting you in person. This way, you will: a). Get to know whether it is a real person blogging here, and b). Apply your own method to verify how trustworthy I am.
Sincerely,
