Rapidfinil lives up to their name - rapidly fulfilling and shipping orders so their delivery times are as good as Amazon Prime! I have depended on Rapidfinil for years and I’m always satisfied with their products, customer service, and turnaround times. Other vendors promise 3-5 day domestic USA-USA shipping and then leave you waiting a week or more while they tell you the order is “processing”. This means you pay more money for longer shipping when you use other vendors. Rapidfinil is the only one that can get things done right! And the one time they accidentally shipped the wrong brand of a product I ordered, they immediately responded to my email and reshipped for free. I was skeptical years ago before I placed my first order but I am so glad I gave them a try. They are my go-to source, especially when I need something ASAP. Thx Rapidfinil!
