Is it a scam? feat. Myprotein

I have that telegram app where you can get discount offer on supplements. They frequently post these myprotein discount updates. Cool right!? But the catch is the whole ordering process in a shady one.

You cant just order item on its app or official website with the discounts. You have to order the item using the link they had provided. That link will redirect you to seemingly ''myprotein'' website. There you have to copy another link to avail the discount. And order.

But i cant just buy the whole process. I want to know did anybody bought item like this.
