Question about Garmin fenix® 8

Hello Galaxus team, I am very interested in the Garmin Fenix 8 and I have noticed that the retailer "Orderflow" is offering the watch on your platform for 1311.54. On the retailer's own website, however, the exact same model is listed for 1000.65. That's a difference of over 300.00. That's a difference of over 300. I am aware that marketplace fees apply, but a mark-up of over 30 % seems disproportionate to me and is very off-putting for customers. Is this possibly a pricing error in the system? I would be pleased to hear from you.
