Do you have the official stores in Serbia?
this stuff is online only and in the usa only right now
There are European alternatives.
Give www.blendrunner.com a look for some of them. http://nutrilent.eu is also one.
But if you want Official Soylent, you either need to buy from a person who has some, use a reshipper or look at sites like amazon, craigslist or ebay
thanks to informations!
