Does the building have offices? like to buy from arg and send there

Yes, but they only receive the packages once you are registered in the building, until you register at the office they do not receive your packages.

Less than half a block away is an AMAZON locker, it is the best option to send packages. The locker is called GABY, it is in the 7 eleven fuel station. The good thing is that you withdraw your package at the time you want, while in the building, in addition to charging you usd 5, only deliver it until 5:00 pm

If they have,

Hello ! If you have a reception and they charge you 5 dollars per box or about what you receive !!! regards
