Hi there guys, need some help if anyone have some experience on this.

I want to buy some supplements about 60 bottles of protein powder from alibaba, im from chile, the provider told me that the package will arrive in about 3 days and will be free shipping, the departure will be from turkey
The payment method he has is western union, kinda insecure i guess and also he said me if im kinda indesicive i can pay 50% of the total price first and once the package arrives i pay the other 50% what do u guys think? Im new on this, is this how it works? Is too amazing to be true i guess

Some help on guys with experience on buying by wholesale
Please!


Thanks!!!
