Enjoy working with Provident. To get the cash discount you must mail a check same day so this makes the process take anywhere from 1-4 weeks. However, I am not in a hurry so I don't mind. It's fun for the anticipation to build for when it comes in the mail.
I would recommend buying the lowest price 1 oz silver rounds that are new. I don't enjoy the sunshine mint rounds that have the security feature as it looks strange to those who are not familiar with it. I used to buy the provident 1 oz coin variety pack but did not want to end up with the Sunshine Mint ones.
