Just an FYI. I (finally) ordered my GF last week through a referral link. It showed the referrer’s name on the purchase pages and my final total listed the discount for the referral. When I got the confirmation email (and credit card bill), the purchase price was without the discount. I’m pretty sure that’s illegal, but GF has reimbursed the difference for me and they’ve added the referral link, which apparently didn’t go through when all was said and done.
Since I checked the purchase price AND the referral info about a dozen times before submitting, if an error could happen to me, it could happen to anyone. Might want to double check your referrals just in case…
