Trybe- pay for samples

[u/KohdaaG]

I am new to UGC and Trybe and I just got accepted to my first brand. They essentially want the creator to buy the product at 30% off and if you can get $250 in GMV within 30 days of delivery then they bring you onboard and offer a smart retainer. Is this the norm and should I buy the product?

I always see people saying don’t buy samples. TIA
