You need a minimum of 4-5 med Supp sales to make it worth while in a 1k mailer. $400-$500 plus gas and time. 3 med supps is doing a little more than breaking even and a waste of time and money.
I do med supps and MAPD plans. It's actually worth it because if I get 5 sales from it that's about $2k with residuals AND a good amount of referrals. Throw in some cold calling and you can have a good month.
I don't know the chick in the avatar. I just like it.....the boobs, and the girl smelling them is awesome.
