I charged $4K for a used car once. PIF a couple of weeks later.
$2500 for a downpayment for a car. The dealer would only let me charge $2500/swip. Two swips two different days, PIF after each swip.
Charged $5000 on Amex PRG. I had the cash but wanted the points. I paid it as soon as it posted. I remember Amex initially denied the charge and the merchant looked at me like I knew dam well the charge wouldn't go through. LOL. I immediately called Amex and they simply wanted me to verify it was me and told me to ask the mechant try again. When it went through the merchant was shocked and started trying to sell me stuff I didn't need nor want. I wanted to say kiss my arse so badly but I didn't.
$3000 on my BCE for a down payment on my SUV I have. I wanted the cash back
2 charges of $21-24k for preschool tuition a few years in a row. No problems with Amex.
i pay my son's tuition monthly, but if I had the option i would do at least yearly, if not longer. Love Amex!
