You have a member for say 6 months. He then charges back 4 of them and that counts as 4 seperate chargebacks.
Or you have a member for 9 months. He stays full price for 2 months that cancels, but takes you up on your "dont leave discoun offer"... stays for 7 more months. Then charebacks 1/2 the discounted months.
Grrrrrrrrrr!!!!!!!!!!!
