Delayed authorization with Amazon purchases

I’ve got a debit card with Capital One and it’s becoming really frustrating to buy anything on Amazon. When I make an Amazon purchase it delays the authorization that comes in. It goes straight in as a payment and then a few days later, an authorization shows up. So I’m effectively out double the amount of the purchase until the authorization falls off. This makes it tough when I’m trying to buy computer parts. I can’t risk buying a $500 CPU and then being out another $500 for a week because they’re trying to authorize a purchase I already made.

Customer service is zero help. I’ve called several times now and they assume I’m disputing the transaction and give me no answers. The guy I talked to today said he had no idea what was happening or how to stop it.

It’s very frustrating. Has anyone else had this happen?
