Right now, there is an additional $50 in T-coded stamps that you choose in your starter kit when you sign up, running thru April.
TAC has a $100 every 4 months minimum.
You can choose your upline based on your needs and how you think they will support your needs. Some uplines are all business, some are strict hobbyists. Its all what you need out of them. Lots of uplines that have a thriving business have downlines that are hobbyist, too!
HTH!!!
