Is there any current running airdrop for this proejct? or any bounty program?

Our planned airdrops are now over, however there is a bounty program you can participate in here: https://storeplex.io/bounties.html

This project is very good I think, although in the announcement a lot of information is lacking. but after I see the sites. that's where I get a lot of information about this project is very useful, hopefully you plan a bounty program for us.

I have a question. Will the buyers and sellers directly trade with each other on the platform of storeplex or will storeplex act as an intermediary like ebay, amazon?

The buyers and the sellers interact with each other via the smart-contract (the blockchain) and not Storeplex personally. We will only involve ourselves when disputes arise.

Buyers can purchase a variety of products and receive 3% cashback on all purchases made using PLEX tokens and sellers can use PLEX tokens to upgrade their account in addition to the extremely low fees.

The marketplace is fully functional, you need MetaMask installed. The instructions on how to use it can be found at the beginning of this thread.

And with regards to the operational costs, those will be covered by the 1% processing fee charged on transactions that do not use PLEX (i.e. Bitcoin, Ether, Litecoin, etc.). The marketplace has not been designed to make a centralised company profit. It has however been designed to raise enough funds to cover the operational costs.

Where can we find link of the social profiles of the team members

The orders are placed on the Storeplex marketplace where they are then despatched/fulfilled by the seller.
