Sold an Instagram to a company for $2,000.00 and a $250.00 gift card. ALMOST sold @sandals to Sandals Resorts for $800.00 and a 5-day, 4-night stay at any of their resorts and a $500.00 airfare credit (like a $5,000-$6,000 value). Unfortunately, they contacted Instagram for legal purposes, so the account, as well as a few others of mine were banned..
I cannot recall, but I sold a method for $500 with @Beats
The most I sold an SM for was probably around $300, but I do not remember.
EDIT: A publishing company randomly sent me 2,160+ Euros before. They charged back, but I got to keep it. I ended up wasting the money and getting extorted.
