One of the campaigns to encourage people to sign up and make purchases is the use of invite codes and friend referrals.
By using a friend's invite code, users can gain up to 10 USD in credit, which, if timed right during Free Shipping promotions, can lead to huge discounts and a chance to get anime merchandise, Japanese home goods or anything you fancy at really low costs.
I am a huge sucker for anything cute in general, so I signed up immediately and bought a few items during the sale.
I ended up getting fluffy alpacasso! earmuffs perfect for the cold winter months that are coming up, Danbo craft tape that is perfect for packing and sending parcels (I adore snail mail), an alpacasso! keychain for my phone and a Levi nendoroid from the popular series Attack on Titan (Shingeki no Kyojin) that I love.
