m0useanswered grow question 4d ago If its like other sites. you give others your code. they use it in checkout for 15% off. and you get that 15% in your account.
One site made it so when you gave out a code you did not get money but credit in their weird currency. and you could only claim it once every 2 weeks and it expired after 6 month or something. and then if you did calim it. it had to be used right away could not stack it up. it was a massive bullshit.
Best to ask fastbud rep on the site and get the DL. or email them. they all have weird fine print you should familiarize yourself with to avoid getting burnt or wasting your time.
