Provident are my go to sellers of silver. Their prices, shipping times and overall buying experiences are some of the best for online vendors. Not to mention they seem to regularly update their stock, they have a number of payment options, everything is clear to understand when purchasing, and they have a great stock of items. The only issue is that customer support takes a long time through email to respond, and when they do, it's someone from India or wherever. If you ever have any issues with Provident, I'd recommend calling them to make sure they process your issue quickly.
