Great service and coa with order
By shannon S.
This has been the most reliable, consistent, and over performing company I've ever had the pleasure of working with. Their shipping is reliable, their products are top notch, and they really, really treat their repeat customers well. I don't think there is a company or service, whatever the industry may be, that I would rather recommend than IDUN. It has FAR exceeded my expectations, their coa's are readily available, and their prices are ultra competitive. Top notch company all around for sure. (Oh, and they provide awesome stickers with each order that are genuinely aesthetically superb) Thanks IDUN!
