AMEX $200 GC Reimbursement seems to be based on amount
Based on my experience of the past 2 weeks, the $200 reimbursement for gift certificates appears to be based on dollar amount. I bought four $50 certificates all at once for $200 and after 10 days no reimbursement. I then bought four more $50 certificates in separate transactions a few days apart and all were reimbursed in a few days.
